Repetitive strings in many modules

[Ask Hjorth Larsen <asklarsen gmail com>]

Hi translators and i18n people

I notice that the string "Quit" seems to have appeared in quite a few
modules.  In total, the msgids "Quit" or "_Quit" (i.e. matching
"^(_?)Quit$") are found 31 times, in these modules:

Why not use a stock label for this kind of stuff?  There are also many
instances of About and _About which I don't recall from previous
releases.
