Switch signatures to use breaks before them

[vr8hub]

Change our examples to reflect that signatures should be preceded by <br/>, not their own <p>. I went back and forth on whether the "eoc" was still correct on the "Yours, etc." before the Gardner signature. I left it, but maybe it should go?

[vr8hub]

We should still specifically mention this somewhere, but this at least gives them an example to follow.

Whether or not eoc (end of clause) belongs there also decides whether we put <br/> there. If Yours, et cetera. is a full clause, then we keep eoc and don't use <br/>. But if it's not a full clause, then we remove eoc and use <br/>. Right now I would say it's ambiguous. If there were a comma after etc., then it would unambiguously be the latter case. But if I had to pick, I would say that it's not a full clause, so we should remove eoc and keep <br/>.

[vr8hub]

Yeah, I agree, I don't think it's a full clause, either. The "etc." could be "truly" or "sincerely" or whatever, but it would still be an incomplete clause when all was said and done. I removed the eoc.

Thanks!
