Saves lots of string construction and storage, simplifies lots of code.
Store the more exotic font-caching bits etc. in a separate store: we
should also pre-render these really and share them.

No need for all these call outs. removeOutdatedTileSubscriptions can't,
Expect it is quicker now and more reliable to trace the tiles being
rendered and count the waiters.

Remove significant complexity; if we need it later lets do it more simply
serializing when we start / finish a session.
Turn off caching for mobile - possibly should kill for single-user too.

When we're doing the prerendering we also need to register
a tileBeingRendered object, so we know that the given tile
will arrive soon. In earlier version of the code, rendering
and sending of the tile was not separated in time, but now it is,
so we need create a tileBeingRendered object even if we don't
subscribe the client to it yet.

Store the tile cache names and drop outdated tiles
times to times, so we can avoid tile rendering / sending to
stuck.
