Restore original settings

I have implemented a restoration functionality that helps the user restore all their previous setting of vim (.vim, .vimrc) and bash (.bash_profile, .bashrc) to their original state before executing this script. The user can choose whether to 'install' or 'uninstall' by specifying the string as a command line argument. The README has been updated to reflect those changes.
Now we also take a backup of the .vim directory in order to supply the original settings in full.
