Update usage of Vundle in vimrc.
Add a few new options to vimrc.

These include:
        Auto-generating ctags upon saving
        Using regular backspacing
                (usually the default, but sometimes not)
        Autoloading after a file has been changed outside of VIM.
Update bashrc.

Add:
        Setting VIM as the standard editor
                (had been default, but not on some machines)
        Setting ls to use colors
                (again, was default, but sometimes not)
Change email address in gitconfig.

Use the AOL address rather than the personal Gmail one.
