Assorted tweaks and adjustments

Fix for a bad mod<>mod<>mod interaction that could happen when the unholy trifecta of stars aligned and the mutons became one and all

A few user quality of life enhancements, and a fix for an extremely rare and very weird visual bug that could cause a muton to end up walking upside down.

The first of several Aura Farming updates.

Small tweaks and adjustments

Updated spawning ruleset heuristic calculations and handling, added fallback systems and a contingency measure to repopulate an enemy pod if somehow a pod with bad data is passed to the Requiem Spawning Ruleset

Complications and optimizations

Bug squashing and stufff

Fixed a bug that could sometimes cause weird random ADVENT Troopers to spawn where they should not.

Moved pod-solving, upgrades, and generation to a more heuristic point-based design that will result in more intelligent difficulty scaling, and drive more organically diverse pod generation. Also enhancing intermod compatability.
