This takes care of everything in the session being able to see the correct
$PATH material - I'd been fiddling with .profile, which is arguably where
this ought to live, but I don't think my prepend_to_path() is valid for
/bin/sh?  I'll probably tidy this up later, but at any rate it solves a
bunch of problems.

Also enables the deletion of bin/firefox-wrapper.

Switch this up for sorting purposes.

Also includes a basic README for the cheatsheets directory.

Demonstrate a couple of gotchas with `empty()` in PHP.

Uses date(1) to parse a given date and use it for the header (by way of
bin/today) instead of just defaulting to current date.

This way the template is accurate when opening other diary dates from
the calendar.

It looks like I went to check whether commandlog was installed a while
back and neglected to actually specify "commandlog" instead of the "foobar"
from the example I was looking at, so commandlog hasn't been running for a
couple of months.

`b foo` puts path to foo in ~/.directory_bookmarks.  `b` by itself opens
an fzf for selecting a bookmark to jump to.  intended as a companion to
h().

Uses xautolock and i3lock.

I'm not even currently using this file, really, but it's a partial list
of dependencies so will be helpful to have for better automating installs
later on.

Uses tabbedBottom instead of tabbed in layout.

I'm not totally sold on this - it maybe doesn't _look_ as cool - but I
think it makes the tabs more noticeable.

Adds a new BPB_BufReadPostOverrides().

Using `moveTo Prev HiddenWS` and `moveTo Next HiddenWS` instead of `prevWS`
/ `nextWS` gets rid of a behavior where cycling workspaces with the arrow
keys will cause workspaces to swap between screens, which has always been
slightly confusing.  If a workspace is already displaying, I'm probably
not looking for it.

It turns out that you can use `:0r !foo` to avoid the blank line I was
deleting in BPB_DiaryFragement() and BPB_DatestampHTML().

Also remove a commented-out YouCompleteMe install.

- switch to iceberg color scheme
  - switch airline theme to luna for console vim
  - add dockerfile, go, and yaml syntax highlight to vimwiki code blocks
  - populate completion from dictionary, set dictionary to
    /usr/share/dict/words and (experimentally) an index of vimwiki files
  - only generate p1k3 templates on lower-case file matches

The `--no-sort` option to fzf effectively gives more recent matches first,
which turns out to be what I want in almost every case.

You can now do `h foo` and foo will be populated as the query, which feels
a bit more natural at times.

...but I'm gonna want that battery indicator on laptops.
