plaintext filter
Inspired by this [terse blog post](http://www.ghastlyfop.com/blog/2008/12/strip-html-tags-from-string-python.html). This filter was designed to simplify the stripping out of all (x)html in a given template var, while preserving some meta information from anchor, and image tags. Why is this even useful? If you have pre-assembled portions of templates, or model fields containing html, that you want to use to populate a *search index* like [django-haystack](http://haystacksearch.org/) you can safely discard all the markup, while keeping the text that should be still searchable. Alt text, and title attributes are worth keeping!
