Note editor/action updates

[orthecreedence]

Basically want to jack the good parts of google keep. I'd like to clean up note "types." There should only be some basic types:

• text
• password
• todo (#42)
• bookmark
• photo

text/password/todo/bookmark all allow attaching a file via an in-editor button/interface (and no distinction between an image file or document...we decide for the user).

photo type is a shortcut to open the camera immediately, and once the photo is taken, drops the user into the note editor with the photo attached and "title" field focused.

some more notes:

• when a file is uploaded, its extension will be saved under a meta field as the file type
• when a url is entered into a bookmark, we run clippo. if the result is just an image with no title/body, we set the image mime type into the file type meta field
• the file type meta field can be used to show previews (pdf/image in the case of attached files, or just image in the case of bookmarks)
  • obviously, pdf inline/previews are outside the scope of this feature (#21)
• should give boards (or "all notes" view) the ability to enable/disable previews
