Fixed the hang when the device is locked.

When the device is locked, we get empty packets in the server.
Now fixed by closing both the lldb and server sockets.
Also after safequit, we need to detach to make the "justlaunch" option to be less error prone.

Multiple bug fixes: 
1. When multiple devices are connected, the detect was not listing all the devices ios-deploy -c -t 1
2. Fixes for issue #75 - non-interactive mode broken lldb and ios-deploy may still be running ios-deploy -b ... -d -I -L
3. Fixes for issue #60 - -L option not working properly ios-deploy will not quit or sometimes hang
4. When multiple devices are connected, cannot use -i option to specify the device ios-deploy -b ... -i -d -I -L
5. Allow timeout when downloading
