SiO2 release 1.1.0

A minor upgrade that fixes up some of the EventBus methods.

The full change list in this release:

• Fixed the EventBus addListener()/removeListener() methods to be static
  like they were supposed to be.
• Added the ability to add/remove global 'dispatch' listeners to the
  EventBus. This is useful for things like lifecycle logging or
  other debug/status related operations.
• Fixed the EventBus to properly check superclasses for autowired
  event listener methods.
• Exposed the DebugHudState's element IDs to make it easier to restyle
  the debug HUD.
