Rolls in render.pl stuff from p1k3.  Now gets deployed system-wide,
to /usr/local/bin.

There's nothing quite like finding a stupid bug in your stupid code you
wrote when you were like 20.

Anyway this turns out to be a nearly-pointless micro-optimization, but in
principle I think it's not wrong.

Stupid.

This reverts commit 4767c623c7.

Something is broken - only rendering a single year.

It appears to be a _lot_ faster to check "is a regular file" (knowable
just from stat, presumably) than a heuristic for "is ASCII or UTF-8", and
it's completely reasonable to treat regular files matching entry patterns
as markup blobs.

- archives -> test_archives
- add archives/gallery_test/

It helps to read the error message.

This whole sub is gross.

Really HTML::Entities should be exposed to templates and used there,
sorta like SparkLib\Template offers $h().

There has got to be a better way to organize all this.

Can be a lot, with a big archive.

...mostly what this does is override the defaults of no headers / no
smartypants features.

Just does an inline substitution for <textile> and <markdown> stuff.

Also adds a bit of commentary.

- strip HTML::Defang
- get rid of old wala markup code
- use Discount for both markup modules (with NOHTML flag in wala)

...also test that it'll render a snippet.
