Prefixes on data constructors are generally an antipattern in Haskell: if you're concerned about name collisions, have clients use qualified imports for whatever modules they need. As such, this removes the T- prefixes from the `Token` and `Context` types. This also renames Context to Scope, which is a more exact and readable name.
