Renamings TreeTransformer -> TreeMap, TreeMapper -> TreeTypeMap

This makes naming uniform between trees and types, and also avoids the clash with
transform.TreeTransformer. The idea is that transformers are parts of phases, and
have logic that is phase-specific. In particular, a context is passed around when
transforming a tree. Maps are simpler, they only have a T -> T apply method.
