vimrc: Vim startup file

I usually create a partition for /home, so whenever I decide to foobar my OS (i.e. do a kernel update on Ubuntu, or start playing with compiz too much) there's no need to copy my home folder to another disk and back again. Regardless of this, there are some essential files which I'd be dead without. One of these is my .vimrc, the startup file for Vim.

My .vimrc file has been organically growing since I started using this editor, a couple of years ago, so I've decided to clean it up a little bit and post it here, just to be sure I won't be loosing it. It's got some tweaks to use Vim as an IDE, feel free to download it and change it or use it anyway you want.
