Bug Fix for Missing Pathogen File Requirement

The vim config was missing the 'bundle' directory requirement, in which
pathogen installs git packages. This may need to be fixed further to
require that directory for each of the git projects installed there,
but if so, then that will be fixed later.
Adds Basic Tmux Config

This adds in a Tmux config that just ensures that the program is
installed. More will likely be added later.
Adds Python Config

This adds a simple Python configuration that ensures the basic
essentials (python-dev, virtualenv, pip) are installed.
