    run: Stop showing full GLib debug messages when not debugging
    
    Currently when running an application, Builder enables all GLib debug
    messages, which means that it always spams the logs, which makes it hard
    to see actual printing inserted in work-in-progress code.
    
    So this commit stops enabling debug messages with the Run button, but
    still shows them when running with the debugger, so there's still an
    easy way to see those.
    
    Additionally, it's still possible to use the Runtime Environment section
    in the Build Preferences to enable those again.
    
    Fixes #1270
