Vim setup

Again, this is mostly a social bookmark to have a trace of what different parts of my configuration files in my Vim folder do. Feel free to steal whatever part you like. Note that not all of these settings will work without additional plugins. The ones I use on daily basis are: Powerline, bclose, voom and latex-suite.

A hint: Since I am using several computers I use Dropbox to synchronize all of my vim configurations thus my .vim folder on every machine is just a symlink to the Dropbox folder. I have moved my vimrc file there as well and source it from the original .vimrc file in the home folder.
