Fix extra "&" in back/forward menu on Mac
Fix extra "&" in back/forward menu on Mac

All "&" characters in the back/forward menu would show up as "&&" on the Mac.

The problem was that Windows uses "&" as an accelerator in menus. We were escaping all "&" by replacing them with "&&".

r36530 added code to the GTK menu to strip the accelerator. Unfortunately those util functions are in GTK only files. Instead of copying that approach I'm simply #ifdefing out the code that adds the extra "&" characters.

BUG=17660
TEST=Verified that back/forward menus look correct.
