[keyboardlayouts] rename ABC and QWERTY layout 'English'

I'm assuming the purpose here is to support regional keyboard layouts for the all different languages. In that case it should specify language because [there are lots of different "QWERTY" keyboard layouts](http://en.wikipedia.org/wiki/QWERTY#Diacritical_marks_and_international_variants). The common way to do this is to have the standard named after the language and "English (Dvorak)" etc.
