Support fish shell!

After some back-and-forth, I'm trialing fish shell instead of zsh as my default
shell. For now, I'm porting the aliases.zsh into config.fish -- defining them as
abbreviations instead of aliases; this preference may change. See the commentary
in config.fish for more information.

A spent a lot of time in zsh and built much configuration, so supporting fish
may take considerable time. Here's some work that remains:

TODO:
- Port functions.zsh
- Port variables.zsh
- Port zle.zsh

+# While I work use a variety of programs, below of some of my more commonly used

+# Commentary:
+# Ideally a file like this would be either unnecessary in the case of a fully
+# embraced Emacs workflow or compiled from some high-level language like
+# Elisp.
+#
+# Most of this was ported from my aliases.zsh file, which I accumulated over a
+# two to three year period. If some of the fish code herein is not idiomatic, it
+# is most likely because I'm new to the ecosystem.
