[PATCH][WIP] Implement Auras

[sanderd17]

I have a little WIP patch for Aura implementation.

It works basically as ranged-based technologies. So you can edit every template value you want.

I also made an AuraManager, basically, that keeps track of all the added bonuses to units in auras. A bit like the TechnologyManager.

As the changes depend on things needed by the technologymanager, some stuff isn't yet ready to be changable:

• Motion speeds can't be changed (at least I've fount no way how). They probably aren't updated during the game
• Automatic heal or damage aura (= negative healing) can't work until the Health/RegenRate is implemented

I also changed the templates of a lot of heroes to reflect there aura description

There are a lot of descriptions that have something in it that isn't an Aura (has no range), I didn't include them, as they should be transformed into technologies (deletable or not).

Changed templates:

Temple and Tavern > added heal aura (doesn't work yet, until Health/RegenRate is implemented)

Female support unit > +10% build and gather speed for nearby CitizenSoldiers
