BIG UPDATE: shell: add profile, move calc and mkcd to files, move

shell-independent config (aliases, functions, env vars, options) to
.config/shell/shrc, make bashrc and zshrc use the same shrc, add TTY
detection for changing caps lock to escape in a TTY, add option for
skipping plugin loading, and maybe a few other things

If this goes well, I'll be tempted to call this version 1.0.  Things
have been very stable for the last few months.  Although, since it's the
first really big change in a while, that might make it version 2.0?
Should dotfiles have big version numbers at all? Probably not.
