Mixu's: Vangheist's Revenge - SFO

A patch to adjust Mixu's Vangheist's Revenge for SFO. Notable Design Changes: Units attributes and stats are properly added/scaled to their SFO counterparts, or similar units. As with any ethereal units, they have 75% physical resistance, no armor and around 30% less health than their normal version. All ethereal units now have Terror, Perfect Vigor and 45% missile resist like all SFO's ethereals. Since ethereal units are stronger in SFO because of these, these units are also more expensive than their fleshy variant. Added SFO's spy/banshee skills to the Ancient Syreen, tweaked some so they work for both factions, and allowed their recruitment from both ship helm buildings. Replaced Dreng Grundadrakk's Perfect Vigor and speed boost from Doomed Slayer with Grimnir's Charge (A charge/speed ability from SFO). Feel free to give feedback. My test save had a good 100 turns but got really boring after the beastmen razed over half the vortex world (the odds of that happening even with SFO...). I couldn't efficiently find people to attack because the world is ravaged and Vangheist cannot declare new wars, so no new level up and no cove for money to support more than 2 middle-tier armies. So I lack high level testing on the 4 unlockable lords and end battle.
