"Run" does not disable the console text box

[David Coles]

When you run a script in the Console using the "run" button of the UI it does not disable the console text input box. This is an issue for long running/slow scripts since a user could potentially try to provide input or try and run the script again (since there would be no feedback from the UI).

Doesn't appear to be fatal though - just will cause confusing mixed results to be printed:

>>> execfile('/home/dcoles/stuff/hello.py')
>>> execfile('/home/dcoles/stuff/hello.py')
>>> execfile('/home/dcoles/stuff/hello.py')
Hello world 8
Hello world 8
Hello world 8

Solution is to disable input like we do for text entry until we finish the command.
