GARRISON <castle> installs 10 soldiers as a garrison in a province.
	The castle must be in the same region (on the same continent).
	Garrisons maintain their soldiers (and any other fighters they are
	given) from the local tax base.  20% of the remaining gold is
	teleported to the castle's owner monthly.
	The castle owner may issue a PLEDGE command to another noble
	who will be the ruler of the land.  The castle owner remains the
	administrator or the land.  Tax revenue continues to be forwarded
	to the castle.
	Status (lord, baron, earl, etc.) depends on how many provinces
	own directly owns, or one has pledged.
	Both the castle owner and the ruler receive location reports
	for the garrisoned provinces.
	The ruler may issue DECREE HOSTILE or DECREE DEFEND, which
	sets the attitudes of the garrison units in every ruled
	province.
