Create room entries for public rooms too so their public state is transferred over correctly when you join it.

webclient SYWEB-3 : Public rooms are bold. Can't think of a nicer way which doesn't clutter the recents list.

SYWEB-30: BF: When switching between rooms, pagination flickered between the top of the room before jumping to the bottom of the page

SYN-40: When a user updates their displayname or avatar update all their join events for all the rooms they are currently in.

WEB-27: We don't need to show the user-count in Recents in the room sidepanel - takes up too much room

Added bing detection logic. Persist the display name of the user in localstorage for use when binging.

Move the notification logic out of an individual room controller and into the general event handler, so we can notify for >1 room.

If an initialSync has been already done on a room, we do not need to paginate back to get more messages

InitialSync: load the 30 last messages of each room so that a full page of messages can be displayed without additionnal request

Use event age to recognise which calls are current and which aren't and hence support answering calls that were placed before we loaded the page.

Comment out password reset for now, until the mechanism is fully discussed (IS token auth vs HS auth)

Added support for the HS to send emails. Use it to send password resets. Added email_smtp_server and email_from_address config args. Added emailutils.

Fix bug where we incorrectly calculated 'age_ts' from 'age' key rather than the reverse. Don't transmit age_ts to clients for now.
