Voice creation for english-us

[buckminster]

Sorry if this has been posted more recently, I didn't see it when I searched.

The latest Linux RBUtility doesn't list "english-us" as a selection when creating a voice file, only "english". Once RBUtility is done creating the voice file, you have to go into the langs directory to rename the file that was created. It seems if Rockbox lists english-us as a language, RBUtility should support it as well. I imagine it would be trivial to fix.
