a number of things, mostly README writeup.

Added a section for each included file in the README, removed the "bugfix" for
profile (there was a bash_profile that was taking precedence), added
debian_chroot back into PS1 (still not sure what it does, but whatever), added
vimdiff as the standard git difftool, removed netrc (and revoked those
paswords. smh), added `-rf` to unwire, and in vimrc: modified 'remove trailing'
mapping to turn off highlighting afterwards.
