Added manual page

So far nothing useful, just some simple info on how to use it and where
to find development stuff.

Updated comments and version number

Version 0.2:
Just some crappy documentation, but I think it gets its own version
number. I like my documentation. Also wanted something for the PKGBUILD
so I don't need people to use pacman 4.1.
