Suggestion: Replace Pathogen with Vundle

Created by: minuteman3

Vundle allows for a more flexible module management system (imo) than Pathogen and would allow the vim packages to be managed without using submodules. In my experience, submodule based vim setups are considerably more brittle and hard to keep up to date than is desirable.

Vundle allows any desired plugins to be specified within the vimrc file. These plugins are then installed from within vim with a command, and are able to be automatically kept up to date along with automatic helptag regeneration. Vundle's behaviour is modeled on Bundler from Ruby.

If time permits I will create pull requests for this change and my earlier issue, #41 asap.
