speeach and behaviour
removed testing messages from empathy. speech is using blocking

difficulties. If I can, it can make our own posting message with proxies
so that we can have better working action queue
made blocking behaviour and speech be possible to specify max time of
blocking
Implemented wait action. It is working, but I want to have worker thread
for action queue.
Created thread for action queue. This will not block GUI thread anymore.

Added more gesture for Empathy study
connect cntl+X to mainwindow's close instead of app exit
