A bunch of config files added.

Bash, Git, PEP8, Pylint, Terminator, Vim.
backup.sh: Script to back up config files

Copies the config files from their original locations to the
script's directory.
install.sh: Script to set up a development environment

Script that sets up the development environment of my liking on all OSs
I use (OS X, Fedora, Ubuntu).

Installs packages, Python modules and Vim plugins, and deploys the
config config files from the script's directory.

Prerequisites on OS X: Xcode and MacPorts already installed.
