* HalTest.cs: GTK test for events using main context
* HalContext.cs: Changed some constructors around, now defaults to
DbusBusType.System, added event system for HAL callbacks
* HalUnmanaged.cs: Added callback set signatures
* HalCallbacks.cs: Contains all callback and event delegates, and
event delegate args classes
2005-07-16 Aaron Bockover <aaron@aaronbock.net>
* hal-sharp: Version 0.1 Committed to Mono SVN
