Subject: [PATCH] ZSH: adds ^n keybinding to expand current word's filename

This is useful if I want to edit a script but I'm not in my scripts
directory. It will look for a file with the name I have typed and
replace it.

for example:
    vim yt<^n>
will be replaced with
    vim /home/jonathan/.bin/yt

The script will first try `which <filename>`, searching the path. If
that fails, it will do `locate "*/filename"` which will search for the
file elsewhere
