xbmc.restartapp + guisounds + deinterlacing

[hagayg]

Most restarts i guess required on first setup stages and afterwards are less frequent.

As mentioned before , I have couple of plugins that get stuck from time to time and i need a "hard restart" for xbmc.
I have implemented solution on other windows xbmc computer using irsuite which kills the process and restart it.

My goal is to map remote key to that task so it will be easier to get out of this mess (especially for non tech guys which otherwise i would have to tell them to pull out the power cord which is less "healthy" than just killing xbmc and running it)
