Fix literally everything :)

Sorry for the megacommit

- Seperate modules into:
  - Compiletime, modules which are only used while building the package
  - Runtime, modues included in the wrapper binary to be compiled on the
    users machine at runtime
  - Shared, modues used in both contexts
- Refactor runtime compilation
  - Completely revamp output paths
  - Don't chdir when invoking ghc
- Require cabal-version 1.14 in cabal file
