Do not set TreatControlCAsInput when using a qglFile as input. 

This allows FxGqlC to integrate with Programmers Notepad.
Now using FxGqlc used as an external tool in PN using the following command:   fxgqlc -gqlfile "%d%d" 
causes an invalid input exception. This is caused by setting the TreatControlCAsInput input to false in an non-console environment.
