1305 Crash clicking on Preferences

a type-o a did a bugfix release on windows and osx. but since the bug fixes i changes some stuff in the SysEx processing subsystem expect problems with that. please let me know, i’ll try to settle things up this week since i have 4 days of vacation before my new job. i’m trying to add the possibility to add LUA SysEx tokens so that each token can be processed in LUA instead of pre-defined hard-coded tokens, it’s a complicated multi-threading issue so it might take a moment.
