move X11 files to gui/
gui: add gtkrc 1.0
add zshrc, zshenv
zsh: environ belongs to zprofile, not zshenv

Not really nice, as `ssh $HOST foo` does not get the environment, but –
meh, at least it is consistent with bash.

Besides, zshenv is read for absolutely all zsh instances, so resetting
environment there would be bad.
zsh: profile: align environ invocation with .profile

Side note: Damn I'm stupid. The [ "$PREFIX" ] avoided the previously
described problem nicely even when this was in zshenv, as environ always
sets $PREFIX.

But again, let's keep it aligned with bash's behavior for the time
being. I might use zshenv, $BASH_ENV, and $ENV to re-add this kind of
"insurance" later...
zsh: use $ZDOTDIR
zsh: remove those debugging echos
bashrc: some consistency in pattern matching
bash: aliases: remove stuff I don't use
