Globe Post HP Req

Implemented a setting that prevents posts by characters below a certain
HP threshold. This is intended to reduce toxic posts by anonymous characters.

The globe seems to be a major source of negative server morale. Nobody is using it
to communicate in a regular manner - I have never seen newbies posting questions
or people debating anything. We will not lose any legitimate use by restricting the posts
to players above a certain HP.

But hopefully, what will happen is an uptick in the types of conversations had on
the globe. A good 50%+ of the posts currently are anonymous mules spewing
insults and toxicity. If people are more or less forced to post only on built
characters, maybe the quality will improve.
