This isn't an entirely side-effect-free refactoring:
- the text of the timeline pills is now either the room ID/alias or user ID/ display name of the linked resource (which means that until we do a roundtrip to get user displaynames, mentions for users not in the current room will have their user IDs shown instead of what was in the link body).
- timeline links to rooms without avatars are now rendered as links
- fixed issue that would throw an error whilst rendering (i.e. unusable client) a room link to a room that the client doesn't know about

These will appear decorated because they are inserted as entities. It was necessary to modify pills to have an explicit linkText that is derived from the `href` being pillified (and is thus no longer the inserted completion but rather the display name (or user ID) or room alias.
For example, searching for `:tong` will now match `:stuck_out_tongue` because the query `:tong` has all non-word characters removed, becoming `tong` and is then matched against the (long) names of emojis such as `smiling face with open mouth and tightly-closed eyes`.
by inspecting whether multiple lines are selected or the selection is empty. If either of these are true, insert a code block surrounding the selection, otherwise insert single backticks around the selection for inline code formatting.
the js-sdk is making some of its APIs asynchronous, and adding an `initCrypto`
method which you have to call.
Particular methods we need to worry about are:
* `getStoredDevice`
* `getStoredDevicesForUser`
* `getEventSenderDeviceInfo`
* `isEventSenderVerified`
_sortedUniq claims to be like _uniq but optimised for sorted arrays - https://lodash.com/docs/4.17.4#sortedUniqBy. But in practice this isn't quite true, so stick with the unoptimised version.
