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
