Subject: Added emote database, which is loosely based off of the NPC database.
 Also changed all emotes to be animated sprites now, and to load from
 emotes.xml. This gives us a bit more flexibility to not only add more emotes
 in the future, but allowing them to be animated as well.

NOTE: This commit, unlike the previous emote commits, breaks emotes if
you don't have the xml file. This will be available on Aethyra soon, but
is not rolled into an update at the moment.
