Text size down is bound to Alt+Shift+- on Linux

[mrvanes]

As the subject says, to downsize the editor text in 3.2.0-dev I need to use additional Shift which actually is _ and size up is broken in the opposite way, that is now Alt+=, wich is the "unshifted" + key.

Addtionally, debug, cue and help pane let the text-size be changed using Ctrl-mousescroll, which would really also be helpful in the editor window.

The following patch resolves my problem, but I don't know if you allways want to fallback to Qt defaults?
