Support Rearm Pool, Limits, and Other Features

[MjnMixael]

Fulfills several feature requests and fixes #7248 .

• The new weapon.tbl entry $Disallow Support Rearm: can prevent a weapon from ever being rearmed.
• Support ships can be prevented from ever rearming, making them purely a repair ship.
• Support ships can draw from a "Rearm Pool" for rearms and when the rearm pool runs out of a weapon, that weapon can no longer be rearmed. Additionally the "Rearm Pool" can be automatically filled based on the Team Loadout Pool.
• If using the Rearm Pool, the mission designer can optionally allow the support ship to reload a different weapon if the Rearm Pool is out of the current weapon. The weapon selected to swap to is based on the weapon hierarchy in weapons.tbl.
• Full FRED and QtFRED support for this feature included moving all support ship options to a Mission Specs sub dialog.
• Added Lua access to the Rearm Pool as well as two new hooks, On Support Rearm Started and On Support Rearm Finished. Both hooks provide the support ship and the ship to rearm as hook variables.

Below are the retail-compatible missions (and a table file) I used to test the features including testing standard support ship behavior.
