Creates an MD5 and/or SHA1 hash of the page body it's embedded in. The hash value is calculated from the wiki markup, so it should uniquely identify each page revision regardless of formatting applied to the markup.

Inserts a wordcount (my format, your format, or no format) into a document. Needed something quick and dirty, so there's some refinement yet to be done.

/*
* Word count action
* Author: Brian Koontz <brian@pongonova.net>

* Replace instances of {{wordcount}} with the number of words in the
* text
* Optionally: {{wordcount preformatted="1"
* pretext="Some pretext"
* posttext="Some posttext"}}
* where preformatted = "1" produces "+++Word count: 9999 word(s)+++"
* pretext is the text to precede the word count (overrides preformatted)
* posttest is the text to follow the word count (overrides preformatted)
* TODO: Probably counts a lot of things it should, and a lot of
* things it shouldn't. Probably shouldn't count actions or other
* special items.
