Changes in synapse v0.7.1 (2015-02-19)

• Initial alpha implementation of parts of the Application Services API.
  Including:
  • AS Registration / Unregistration
  • User Query API
  • Room Alias Query API
  • Push transport for receiving events.
  • User/Alias namespace admin control
• Add cache when fetching events from remote servers to stop repeatedly
  fetching events with bad signatures.
• Respect the per remote server retry scheme when fetching both events and
  server keys to reduce the number of times we send requests to dead servers.
• Inform remote servers when the local server fails to handle a received event.
• Turn off python bytecode generation due to problems experienced when
  upgrading from previous versions.
