Modding reanimating priests

[sube]

And also:

- #nodrain: this unit's research is not affected by drain scale (just like a Ulm smith)

- #patrolbonus is not yet implemented right?

- #seasonal <season>: unit gets extra hp during a specific season (like winter wolves, simmer lions, red guards etc)

And i had a fourth one too, but right now i can't remember what was it. Damn old age...

Edit: Ah yes:

- #heroname <name>: forces a hero to have a specific name
