menubar visibility and kdevelopui.rc

[René J. V. Bertin]

Hi,

Some of you know that I use Qt's Xcb platform plugin for testing on OS X, and so 
I start KDevelop in "X11 mode" with a certain regularity. I have thus patched 
main.cpp so that it doesn't use the Mac native menubar with the Xcb QPA so that 
I have access to the menubar.

That works but not very reliably; it seems to be coupled to the kdevelopui.rc 
file cached in ~/.local/share . Does KDevelop have a hidden feature to (un)hide 
the menubar?

Additionally I noticed that if ~/.local/share/kxmlgui5/kdevelop/kdevelopui.rc 
doesn't exist, it is copied from ~/.kde/share/apps/kdevelop/kdevelopui.rc
which is quite different than the file shipped with KDevelop5 .
