Fixed lua error during some type of "a player leaves"
Made the stationary units only have regen +4
Fixed a bug with Regeneration and Siphon Strength
fixed mud touching some units (e.g. dragons)
supporter hat tweaks

Let myself get the supporter hats without the magnanimous trait.
Also magnanimized players based on original nick,
   even if they change before their turn 1.
Lowered CoP price a bit
Buffed Change Terrain duration
Reduced Arctic Drakes arcane resistance a bit, for style reasons

I didn't like the fact that a cold-themed drake's cold resist
   wasn't as big as the other buffed resist. And the main point of the
   arcane resist buff was just "don't be especially weak to it"
Made Travelers better on snow, because why not
maybe fixed a bug involving banishing units
Hopefully always designated me as author instead of magnanimous
Fixed issue with wizard swords getting wrong damage amount on e.g. dwarf apprentices
Made Mage Shielded wizards not waste shields on damage-only spell swings
fixed unnecessary global access
