* Fixed several obscure deadlock issues.
* Savestate actions block; such that only one load or save is permitted at a time.
* Savestates now work through temp files, so that the existing file is not corrupted in case errors occur.
* Exiting the emu while a savestate is saving will still save the state before completely quitting.
* Plugin init errors are handled more gracefully.
Developer Notes:
* Added some event diagnostic trace logging stuff.
* More preliminary work on memorycards -- moved them to their own dialog box and started implementing things, but still a lot of work to do before it's ready for use.
