vim: cleanup vimrc, add more comments
add a nice README file
git: alias amend = commit --amend
Terminator: make terminator behave more like xterm

(because I like the simplicity of the xterm UI, but Terminator has more
features.)

Unfortunately, Terminator does render Terminus Bold as Terminus Regular at 8pt,
but I can live with that for now.
xchat: some more user-defined commands (besides the default)
xchat: save config as-is
