Move groupNames mask definition to its user groupNames was declared in compat.c as a global to anything which included compat.h (for which groupNames was its sole reason to exist), but only ever used in indicators.c. Which is kind of fortunate, given that e314931e removed identical definitions of groupNames (as integers, not masks) from both action.c and symbols.c.
