Mothership Rework (Polished)

[SirChuckOfTheChuckles]

Client-side PR: archipelago-sc2/Archipelago#17

Overview

This PR looks to implement two other Mothership, the Aiur Mothership and the Purifier Mothership (including both having Mothership Cores), as well as a variety of items to the Tal'darim Mothership. A majority of the items are implemented in-game differently by having the player spend resources on the actual Mothership to unlock these abilities/passive upgrades, instead of having them be automatically unlocked on the unit for the player. This was done for the following reasonings:

1. Balancing: Units like the Tal'darim Mothership are already considered one of the strongest units in the AP-Protoss roster, with the only item they have currently (Integrated Power) being put in overpowered items just to balance them. With the costs needed for the abilities and upgrades, it's meant to make sure the Tal'darim Mothership doesn't become even more OP than it is, forcing at least a moderate cost-sink in order to get the upgrades.
2. Experimentation: A semi-frequently requested trait for some upgrades is to have them actually be bought instead of just outright unlocked during a mission. This update is meant to experiment on that idea by having the upgrades be installed, and to give the Motherships a plethora of abilities while only making sure they are allowed to use 2 of them.
3. Theme: While normally requested for Battlecruisers, players have wanted the fantasy of buying multiple upgrades for a Capital-class starship and have it slowly become a superweapon, so I wanted to try to fulfill this fantasy with the Motherships.
