Don't leave semicolon behind after consuming Æ

[rgrove]

Looks like someone snuck in another character reference with the same problem that was fixed in #249.

Oh wups, forgot to merge this. I'll pull the patch in to trunk so that it's fixed at HEAD; I am still somewhat curious as to why this caused it, as switching to Ragel was supposed to ensure that it always matches longest-match-first rather than first-match-first. If that's not the case there may be other regressions if any other entities are changed, and it may be worth writing a testcase to catch them.

@nostrademons: I think the cause this time was that AElig; wasn't even in the list of entities, but AElig was. I double-checked when I sent the patch and didn't find any other no-semicolon entities without a semicolon companion, so hopefully this shouldn't crop up again unless new no-semicolon entities are added.
