Push server connection thread improvments

I was looking at the code in the for the webSocket threads and realized I could simplify it by re-arranging some things. I also added some logging to make it easier to see what's happening in the future if there are disconnects. I'll add some code to pass in a log function so we can remove the common.py dependency.

Anyway this seems to fix #13, though I'm not sure why :)

When I unplugged my Ouya (which causes the socket to disconnect pretty quick), the re-connection code worked fine (and it was easier to see with the added logging). I'll have to let it run for a while to make sure the original ```[Errno 104] Connection reset by peer``` I was getting before doesn't somehow still break it.

I also shortened the sleep time on in service.py for faster shutdown response. This doesn't seem to have an measurable effect on CPU usage, but I can set it back if you would like. I also made the reconnect sleep only wait for 100ms between abortRequested checks, which shouldn't be a problem since this isn't a long running loop.
Why you have added the thread name? Only for understand new things :)
