zsh configuration proposal

[Eric Hattemer]

All bindkeys are now added, and I fixed the prompt/bash problem by 
replacing instances of the var PS1 with PROMPT.  I updated the prompt 
perl-gtk thing too.  Someday soon I'll put all the prompt variables in 
there.  New versions are at http://isd.usc.edu/~ehatteme/zsh .  The 
bindkeys seem to work (in a terminal that doesn't respond to home and 
end internally).
