Genie Python: Add run and queue script

As an instrument scientist I would like to be able to queue scripts on the script server from a console. As such I would like the following two commands:
* g.run_script: Runs the given script client side (and doesn't load the functions into the namespace like load_script)
* g.queue_script: Queues the script on the script server.

These methods should have the same behaviour for each script other than one being client side and the other server side.
