Whole lot of changes

I added quite a bit of new things:
- Dub support for sourceLibrary in any project (package.json)
- Vibe.d Fibers, ConnectionPool features work
- All sources are verified in DMD 2.064.2, Win x86 / Linux x64
- Postgresql 9.3.1 tested, locally and remotely

The modules were renamed as well because some of the functions were created as global. The files were put into subfolders because dub didn't allow them to be in the current folder. Yes, there are lots of radical changes but this project was completely broken, so I don't think there will be any complaints about it.
