Add -language command line option for overriding UI language

Browse Source 
I run Qt Creator in german, but for responding to questions and
generally looking things up I regularly want to run it temporarily in
english. A command line option makes that easier than having to start Qt
Creator, navigate to the settings, and restarting it, and doing the same
again to revert back to german.
