Added try/except for setting signal handlers.
Setting signal handlers from inside a thread is not supported in Python, but some applications need to run Sleek from a child thread. SleekXMPP applications that run inside a child thread will NOT be able to detect SIGHUP or SIGTERM events. Those must be caught and managed by the main program.
