I've added a minimal change for running a module in the editor with command line arguments. 

Some notes:
1. The shortcut key (F7) can be entered while on the shell window.  As of now, any of the Run menu shortcuts can be entered, so I didn't fix that bug as part of this issue.
2. I'm not saving the arguments in any way.
3. I didn't (yet) make the change to print the command line arguments in the shell or to add it to the status bar.
4. I didn't make a change to get the sys.argv values from startup.
5. I added a single menu entry and not a cascade of different custom run options.
