html validator middleware

[Brian St. Pierre]

I recently hacked together a small middleware that validates all
outgoing html and if it encounters a validation error, throws a 500
status code and error page with the validation error message(s) and
html source.

Similar in aim to Luke Plant's Validator App (http://lukeplant.me.uk/
resources/djangovalidator/), but lighter weight.

Requires python 2.4 (for the subprocess module).
Requires the offline "validate" utility for HTML validation from
HTMLHelp.com, or its equivalent.

Available here: http://bstpierre.org/Projects/HtmlValidatorMiddleware/

Comments & questions welcome.
