Separated vanilla version from HIP version.
Adjusted requirements.
Made possible wars visible even if requirements not met to declare them.

Reformed pagan vassals follow the same holy war cb rules as any other organized religion.
Piety cost increased for decalaring holy war for reformed pagans (from 100 to 200). Piety amount requirement for hw cb (400) for every organized religion (increased for pagans from 200 and every other religion from 0).

Validation of ongoing HW now checks only for (one has to return true): independence, king tier (regardless of traits), existance of one of the required traits (ambitious or zealous).

Holy War CB allowed or disallowed for vassals depending on their traits.

Holy War Cassus Belli allowed for vassalized kings.
