EditPlayerGUICard resets to the correct tab

For example, if adding a class point, the EditPlayerGUICard will refresh
with the Classes tab open.
As well, all tabs will display an exclamation mark if there are points
to be spent, ie. the Skills tab will display "Skills (!)" rather than
just "Skills" if there are skill points to be spent. The exclamation
mark will be removed upon refreshing if there are no more points of that
type to be spent.
