LemurProto version 1.10.0

Minor update.

Change log:

• Modified OptionPanelState and OptionPanel to automatically request/release
  the cursor using the new GuiGlobals.request/releaseCursorEnabled().
  This may be irrelevant if OptionPanelState is converted to use PopupState
  as it should be.
• Set sourceCompatibility to 1.7 and turned on warnings.
• Fixed some issues related to deprecation warnings and 'unchecked' generics
  warnings.
• Part of that was a conversion from extending the internal BaseAppState to JME's
  BaseAppState which is a potentially breaking change for any application code
  that extends Lemur app states but expects enable()/disable() instead of
  onEnable()/onDisable(). In this case, just OptionPanelState.
