Allow adding / removing tags in post editor about quill HOT 1 CLOSED

Potential alternative chips input component for the future: https://github.com/pchmn/MaterialChipsInput

The current chips component we use is quite simple and fulfills like 95% of the UX goals I desire, while all the full-featured components I tried suffered from several issues or lacked important features. The only slightly ugly things with the current implementation are: (a) it always displays a trailing comma, and, (b) I couldn't get a 2-character delimiter like , (that's a comma followed by a space) to work.

UX considerations to keep in mind when evaluating alternatives:

• Chips/tags should be completable by typing a delimiter like a comma (NB: Ghost tags can contain spaces so that won't work as a delimiter)
• Chips should be delete-able by tapping backspace when the cursor lies to the right of one
• Must support auto-complete using a pre-populated list of suggestions
