FB are no longer supporting Draft.js; perhaps we should switch to Slate.js or similar

http://slatejs.org/#/rich-text looks really nice

Slate does look very nice. I don't think it supports Entities like draftjs does, but looking at it I think it'd be possible to write a plugin for those sorts of things (if someone hasn't already).

i think it effectively does support entities via plugins, which are trivial to write. I’ve made a stab at this in my spare time on matrix-org/matrix-react-sdk#1890. It so far going fairly well: first of all commenting out all the Draft stuff, getting it working again pre-RTE but with Slate, and then uncommenting the Draft stuff again as it’s ported to Slate. So far Slate feels way nicer to work with, and has already fixed various weird races when trying to type and paste into the editor where characters would appear out of order, which was driving me nuts.

fixes #4708 already for instance
