Niels Martin Hansen ef4021f757 Make error handling in DSound2 audio player more robust. When an error happened in the playback thread, the error_happened flag was set, but was never cleared when the error was detected in the main thread. Furthermore, the main thread didn't act upon the error besides showing it, it kept acting as if the playback thread was still alive and playing, causing the error to be triggered continuously requiring you to kill Aegisub to get out.
Made the error_happened event reset itself after being checked so the check only succeeds the first time. (The playback thread returns from its threadproc upon error.) Mark playback thread as dead when error is detected, such that a new thread will be created next time playback is started, effectively making errors non-fatal.
Playback still works as expected, however I haven't tested what actually happens now when an error occurs.

Originally committed to SVN as r2968.
