Command line flag for run command to not open browser tab

[JoshWhitePA]

My development process requires me to use an API key (?apiKey=) to log into the app in localhost. Every time I execute rally-app-builder run it opens up in a new tab without the API. I close that tab and refresh my page with the API key.
This can be very tedious and slows down development.

Is there a reason you need to run the run command over and over? I'd think you could just do that once at the beginning and then just refresh that same browser tab as you are working and making changes?
