first cut of improving UX for deleting devices.

This adds a 5 minute auth cache to speed up the process of deleting
old devices.  It has the following nastinesses (mainly due to being
written on a flight whilst juggling kids):
 * the auth cache is done as context attached to MatrixChat.
   one could argue that it should be per-client instead, but we don't
   yet have multiple clients.
 * the auth cache is only maintained currently in DevicesPanelEntry
   (i.e. set & invalidated).  One could argue that it might be better
   maintained in InteractiveAuth.js or a dedicated cache object
   abstraction, but given the only use I can think of is when managing
   devices, perhaps this is good enough for now.
