Debug: Add possibility to specify amount of gold in TakeGold cmd

Currently in GiveGold and TakeGold commands in debug.cpp we only have
a possibility to flood our inventory with gold, this patch adds a
possibility to either specify amount of gold to be added or just
write "max" which will preserve native functionality of those commands,
by clearing all gold or giving max gold possible (depending on the
amount of free slots in inventory).
