UI: add optional tip callback to uiBut, and use it for per-item tooltips in
UIList.
When defined, uiBut->tip_func is called when button's tip is generated. This
allows
for advanced, dynamic generation of tooltips.
For now, only used by UIList, which can now optionaly use a given string
property
of each item for its tooltip.
Thanks to Campbell for the reviews!
