Forgot to detach accelerometer callback thread
Testing a new way of syncing joint events
More testing...
Move wait works implemented in CPP...

but we still have issues. It seems we cannot avoid running callbacks in a
separate thread if those callbacks must call into Python.
Merge branch 'f/test-joint-event-thread' into f/cpp_moveWait

Conflicts:
	src/linkbot_wrapper.cpp

Also fixed hang-on-exit and several other bugs
Some changes, debugging
