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.

I don't really remember what shape any of this is in.  Just sort of poking
at it.

Start using top-level headers for entry files.

...plus random whitespace changes.

Moar memory, less potential confusion doing it in place.

Also made it send errors to the log instead of displaying them.

Never really did anything with the idea.

Sometimes it becomes painfully obvious that you never ran the tests.

This is cheesy, probably XSS vulnerable, and some things are still broken.
