Tells QT not to translate shortcuts.

There is currently a problem with crowdin. It asks to translate
shortcut. I assume that actually, shortcuts are intended to remain the
same independtly of the language, and thus that they should not appear
here.

I kind of assume that crowdin gets the strings to which _ or ngettext
are applied. So I wanted to ensure that none of those methods are
applied to shortcut.

The python file containing those shortcut are generated from .ui
files, used by QTCreator. I thus changed those files to indicates that
shortcuts should not be translated.

I assumed that shortcuts are strings containing either only "F(digit)",
a single letter, "Alt+" or "Ctrl+". I may have missed other shortcuts if they
exists.
