post_class for public custom taxonomies

[sillybean]

post_class() should include styles for custom taxonomies.

Nice enhancement. Can probably clean up the existing taxonomy code there in the process.

Going to leave the needs-patch on there. Let's reduce the code a bit.

We also need to check that we're hitting the cache on that.

I thought so too, but it would change existing behavior, since tags print tag-name now and this would print post_tag-name. Could throw in an if just for tags, I guess.

Indeed.

Patch updated. This replaces the existing bits for categories and tags in a way that's consistent with the old behavior.

Not sure about the cache; this is more or less how it was done before.

Finally found a moment to go through all the relevant functions, and it looks like they are hitting the cache whenever possible.
