Gcalc - Adding verbose tooltips

[gnome-devel deaddog org]

Is it OK to replace the tooltips of register-related buttons
in gcalc into something more verbose? Currently they are:

STO -> Store
RCL -> Recall
SUM -> Sum
EXC -> Exchange

They don't describe much what the buttons mean. But will the
attached patch conflict with gcalc doc?
