2.05.4:minrog:11 Validator #171 Events

Chipping away at some event errors.  A few of them are present even in
the vanilla files like religion = norse and religion = tengri when those
religions should have _pagan after them.

It's getting progressively harder to find errors because my guess is
that about 500 of the "errors" reported by the Validator are actually
false positives due to incorrect scope analysis.  Hopefully that can be
fixed soon.
