Allow a personal reading list collection

[jkomoros]

While reading a deep-linked card you might come across links you want to read, but not right now. The Ctrl-Click behavior loads a whole other tab of the app, but ideally you'd have some way to add to a current, personal (no need to persist) reading list.

If you navigate to a card and then back (not by way of arrow keys but via link clicks) the UI should tell you about the feature

[jkomoros]

Should basically just be a tag, but specific to the given user

Should it be a sub collection on user or stored in a similar way as stars and reads?

Will need to do account merge logic for Anon/sign-in users

Have a button below the card that shows three state: add to reading list, on reading list and a done button if it's on reading list and you're in the reading list view

Ctrl click on a thumbnail or card-link should add to reading list (with animation of it to reading list to make it clear what's happening)

Allow reordering of your own reading list (as admin can do in sections today)

Have a reading list link in nav bar

Card-thumbnail and -preview should show whether the current card is on reading list

Have a tip about reading list once you've clicked on a few links

When you are viewing reading list and hit done on the current card the thumbnail should gray out showing that it's off the list even though it doesn't disappear immediately (this mechanism ideally would happen with any diff from pendingFilter to filter)

Reading lists are unlike tags in that they actually do encode an order. Currently the default orders come only from the active set, the first item in the URL (and currently always all). That implies that reading-list is another set entirely. But there are some use-cases where you want a reading-list as a filter, so I guess it makes sense to also create a filter for reading-list, like we do for sections and tags, in makeFilterFromSection

• [x] Create security rules for reading_lists
• [x] Connect up readingList into state
• [x] selectUserDataIsFullyLoaded should also look for whether the readingList is loaded
• [x] create an addToReadingList action
• [x] create a removeFromReadingList action
• [x] Add a button in the UI to add to or remove from reading list
• [x] make reading-list a base set name
• [x] Make it so if you un-check an item when viewing reading-list it doesn't go away if you're viewing the reading-list set (this is similar to #109, but for the base set)
• [x] Make it so if the reading-list item will uncheck it that we render it as ghosted even in base set
• [x] Rename COMMIT_PENDING_FILTERS now that it's more general
• [x] make reading-list a filter as well (similar to sections and tags)
• [x] Add a nav-bar item for your reading list
• [x] If you view the reading-list with no items in it, it should show a tutorial card about how to use it
• [x] Add tool tip on the reading list button
• [x] Card-links that are already in reading list get different styling
• [x] Ctrl-click on a card-link adds it to your reading list
• [ ] Tooltip text on the add to reading list button should change based on whether the thing is already in the reading list
• [x] Is there a way to refactor the security rules so that reading_list//updates don't need to also have an owner field on them to allow them to be written? Also wouldnt' the current rule set up allow someone to technically add an erronous update on a reading list they don't own? I guess the approach is just to check that the overall id of the parent (the first item in list that matches {document=**} matches the id of the auth user and that's that, don't worry about owner fields in the document itself (and remove the part where we set owner on the update field as well as in addToReadingList and removeFromReadingList)
• [x] Card-thumbnail should show whether the given card is on the reading list
• [x] Ctrl-click on a card-thumbnail adds it to your reading-list
• [ ] Make it so ctrl-click (on mac) on thumbnail doesn't show right-click menu (it's a bit harder than it might otherwise be because the event handling logic is separate from the card-thumbnail)
• [ ] Makeit so reading list icon and ctrl-click behavior on card-thumbnail works in the find dialog (also reads and stars don't show up there which is silly)
• [x] Card-preview should show whether the given card is on the reading list
• [ ] When a new item is added to your reading list it should animate over to the nav, to make it more clear what's happening (perhaps with a fading-text style component like in boardgame)
• [x] The nav-bar item should print out how many items are in your reading list (also covered in #166)
• [ ] Do account merge logic for anon/signed-in users
• [ ] Update the text of the about-reading-lists card to keep it up to date with how reading list actually works
• [ ] Support reordering if you're viewing the reading-list set
• [ ] After you clicked a few links show a tip about using the reading list
• [x] When you're on the reading list, things that you just hit done on should be grayed out (issue #191 )
• [ ] Consider auto-removing items from list when you read them
• [ ] Consider showing a different button if you're viewing the reading list (a done button) where the "add to reading list" button goes (it's probably fine the way it is)
• [ ] A feature to add or remove all items in the currently active collection to the reading list (e.g. a button to show)
