* Fixed some minor bugs when processing idle events.
* Plugin Load/Init/Shutdown/Unload are all called from the Main/UI thread again; this is important for plugins that issue popup warning/error messages.
DevNotes:
* Added ScopedPtrMT, a multithread-safe version of ScopedPtr.
* MTGS errors are still not handled as gracefully as they should be; namely the MTGS thread doesn't restart itself (it's on the TODO list).
