more clean shutdown order

[spali]

It's maybe just cosmetics, so don't rate it with high priority. When Homegear shuts down, either events get's still executed after the rpc server stopped accepting connections or still running event tries to connect. please make sure:

• stop event processing before stopping rpc server (if not already)
• or the other possibility: wait until all running events finished before closing rpc server. I would suggest to only wait a short amount of time (maybe 1 second). This should allow a usual event process to finish, but don't prevent homegear to shutdown in a reasonable amount of time if there are events executed which requires a lot more time. Don't know if there is would be a more robust logic to shutdown with running events, where Homegear can't know the estimated execution time.

Here an example of my log.

Stopping event processing before stopping the RPC server makes absolutely sense. Changing this was easy ;-). I'm waiting until all events finished processing before stopping the RPC servers.
