ZeroTH - remove unnecessary TH dependencies

TemplateHaskell is fairly useful for generating new Haskell code. This, however, can incur a dependency on TH on subsequent uses where none theoretically should exist. ZeroTH solves this by scanning a file for top-level TH declarations, evaluates them, removes TH imports, and outputs the resulting code.
