WIP: Guild Skills: Restore, Regeneration and Battle Order
@Micksha said he liked those skills.
The code in hercules upstream only allow them to be used on GVG maps and Guild Castles. This hook bypass this check.
It may have a bug of not checking if char is in a guild and is guild master.
BUG: Currently only works if you use unitskill() to invoke them. ManaPlus won't even cause the ShowWarning() to produce output.
Remember to remove these debug markers later.
