- add zsh syntax highlighting plugin
  - add more color options to prompt configuration
  - tweak inertia prompt colors
  - refresh prompt periodically (this may need some thought)
  - add Alt-Up, Alt-Back for dir navigation
  - automatically rehash to pick up new commands for completion

- stop erroring on utf-8 output
  - use the right syntax for redirecting stderr
  - don't display sections with no output
  - indicate vimwiki path

Also removes xmodmap from xmonad.start.

addscript: add a new script in ~/bin.

f-to-c: convert degrees Fahrenheit to degrees C.  A wrapper around
units(1), because I'm always forgetting the syntax for this.

put-mv-notes: move the currently yanked file to ~/notes.

Use fzf to select files from changed files (including untracked) in a
working tree.  Thanks to @tomasino@mastodon.sdf.org for the git subcommand

Serve the current directory.

Shells out twice in a silly way.

Adds a --file option that will either:

  - pull the date from a vimwiki filename
  - pull the date from a p1k3 entry path
  - pull the day from file's mtime

Aggregates some stuff by date range.

This is Tyler's bash version, just because it doesn't have much in the
way of dependencies.
