update tag creation dialog style

[ezl]

Several parts to updating the tag creation popup/dialog:

• [x] Always display the "create tag" part for creating new tags. This is because currently you cannot create a tag that is a substring of an existing tag. As an example you may first create a tag called #foobar, then try to create a tag called #foo. When you do, it will autoselect the previously created tag #foobar that includes the shorter, new string. In order to solve this, we need to always make "create tag" an available option
• [x] Allow up/down key bindings to select options in the pulldown. Currently, the autosuggest for tags simply shows the first valid string match at the top and highlights that one, while displaying other substring matches below it. instead, try the twitter interface for creating a tweet, then add a hashtag. when the autosuggest dialog displays, you can press down to select other options. this does NOT update the typed text unless it is selected. similarly, you can try google's search autosuggest and see how up/down keys select other options. Further, this will allow the user to key down to the "create tag" option at the bottom to create tags that are substrings of existing tags (problem described in previous part)
• [x] in the list of matching tags, match these by (a) of course all tags that match the typed text (b) sort these by order of used frequency DESC - so if 3 tags match, the highest one should be the one with the most currently incomplete to do items
• [x] Update the placeholder text from "type to add tag..." to "type to add tag or press ESC to cancel"
• [x] Update appearance of "Create tag" part of pulldown: https://monosnap.com/file/WkKYdN7Vo4QK7fhX9eXXGBnamx75ls

Instead of always showing the “create tag” option, I found and implemented a solution that will allow creating a tag even if it is a substring of an existing tag. The “create tag” option will only show up if an exact match is not found.

What do you think @ezl

Sounds good @yassinya - go ahead and roll it out then I'll evaluate once live. :)

You can try it out now @ezl , it is live!
