Remove thread dep

Hello Coderholic,

Here is what's in my pull request. I should have sent 2 but I needed the second one to fix the first one :).

Fix after Py3k migration
----------------------------------
There was a big after migration to Python3. The "updateStatus" Thread fell in error due to byte to str transformation. I fixed this. Pyradio is not depending anymore upon "thread" obsolete API but use the "threading" one.

Logging API used again
----------------------------------

I also reintroduced the usage of logging. I think in a future commit, I will propose you a way to start pyradio in debug mode so that these logs can be attached in the issue tracker.

@+,
