Fixed Indentation Error in notify.py and indicator server in hotkey

So now when someone sets up LiSpeak for the first time, the indicator-server and notify servers start automatically i.e. during the setup. However if someone quits the server and presses the hotkey again for which the user has configured a keyboard shortcut, the indicator server doesn't start. So I have added some code in the hotkey file which checks if the required servers are running and starts them if need be.

The only problem that I am facing right now is when I run the hotkey script, it starts the server however I don't see the "App status" being updated for the first time in the app indicator. This happens the first time when the hotkey script starts the indicator-server and the pycmd script sends signals to it to update the app status.
