Subject: Reimplement AbbrevMap, and implement Multimap

This reimplements the old AbbrevMap structure as AbbrevMap2, and created
a new Multimap structure as a apart of it.

Multimap is exactly what it sounds like; a map that allows multiple
values for a given key. The only real thing that is different about it,
is that if you add a key-value pair multiple times, you'll have to
remove it multiple times.
