Added a rm:add_pre_setup_callback() function for modders to use.

Cleaned up a lot of the comments and removed unused code so that the mod looks halfway decent for modders who want to see how it works.

Fixed Caps not working when recruiting from a Herdstone.

Fixed units not being counted on the summary meter tooltip if they were present in the queue but absent from the army.

- Fixed an issue where points were not properly refunded after disbanding units.

- Recoded significant portions of how the mod works to make it less needlessly complicated.
- Removed commented out code, junk code, and other such things.

- Fixed issues where stale armies were not getting refreshed, which caused players to lose points when disbanding units, losing units in autoresolve, or merging units.

- Fixed an issue where the unit pins would be mistaken as recruitment orders. The pins are usable now.

- rm:can_upgrade_unit_to_unit(char_cqi, unit, unit_upgrade) added

This command evaluates whether replacing unit with unit_upgrade would be allowed. It is used to support other mods.

The Loan Units table in the API now optionally accepts a list of subculture key strings instead of a single key string. This adds the unit to all the subcultures in the list and is used in Vanilla to support Ogres.
