A step towards getting rid of zaps.
Don't crash on 0-hd shapeshifter simulacra.
Give every orc priest a portable altar.

You also get to pacify one orc band per game: the band you surrender to will
let you live.  Obviously, abandoning and reconversion doesn't work (even if
you're still allowed to repent).

Unlike HOPr only, this allow to play more interesting combos with Beogh.
Converting when you (maybe!) get that Orc:4 altar is way too late to get
much use of Beogh.
Let orc priests get preachy when they see you.
Kill HOPr^Beogh.
Let priests of Zin follow Beogh.

To the stalkerdom!
Improve wording of the "Convert to Beogh" description.
Fix punctuation.
Generalize the check for monsters allowing Beogh conversion.
Add formatting fix.
Constify.
Only orcs can be Beogh's Witnesses.

I demand the xp for that ogre back!
Fix check for orcs allowing conversion: everywhere else checks for genus, not species.
Don't prevent hot Lava Orcs reading books
Massively reduce changes of artifact staff generation
Orc priest speech improvements.
Fix wording.
Update changelog through 0.13-a0-1380-g03ef21a.

Probably I've missed some significant things; if so, go add them in!
Some other important highlights for the changelog.
Added parentheses to gargoyle petrify-stat-loss.

Now their stat loss is based off of maximum damage reduced in a single
hit, instead of the unreduced size of the largest single hit.
There were missing parentheses resulting in no-op arithmetic.
