Demolition Pack DLC support.

REQUIRES STARTING A NEW GAME
(some of the changes will not appear in old saves, or even might prevent old saves from loading)

- fixed typos
- clarified some tooltips
- rolled back some of the AdMech Lord of the Machine Cult ability changes to avoid potential AI lockup
- fixed Tank Commander abilities that could result in a crash during AI turn
- properly separated AsMil Guided Munitions ability (Tank Commander) from Aura of Discipline (Lord Commissar)
- flyers now appear flying (added proper unit offsets, same idea as in Timmeh's Flyer Rescale mod)
- terrain changes:
-- Bedrock is less annoying (still not removable but doesn't prevent removing other features)
-- Brush doesn't apply "swarms" debuff to units it shouldn't affect in the first place
-- Brush is -1 range instead of max 1 range, so range-boosting still works in it
-- Rocks do not provide buffs to flyers
-- Wire Weed doesn't affect Canoptec Wraiths as intended (vanilla bug)
- fixed attacks/hp/healing scale:
-- Items: Zoat Hide Jerkin, Uncreator Gauntlet, Jokaero Digital Weapon
-- Drukhari: Reservoir of Pain, Feast of Torment, Field Repairs
-- Eldar: Mind War
-- SM: Machine Empathy
-- CSM: Noctilith Crown (as well as Neutral version)
-- Orks: Dok's Tools
