Major refactoring

[igorw]

I realize this is quite a big pull request with lots of changes. This is how I would make a library that's more re-usable. A summary of the changes I made:

• lots of shifting around files and directories
• use the "Mongrel2" namespace
• follow the PSR-0 naming convention (this allows autoloading)
• add a composer.json so it can be installed via composer
• improved README

My hope is that with these changes (most notably the PSR-0 and composer ones) we can get more re-use of this code. Right now the AiP guys implemented their own mongrel2 parsing (see here). Same goes for photon.

I say it's about time someone hit them over the head with a baseball bat. Just kidding, but we need more re-use. Feel free to just pick out parts of these changes if you don't like them.

That is awesome, thanks a lot - I'll see what I can do in the next days.
