Hyperactive

If you go to http://london.indymedia.org/groups/show_all and look at post fact media, their description is short, and if you look at the source, it actually truncates in the middle of a tag, which is not great.

So be nice to truncate in a more clever way that only counts characters outside tags ...

If we had a truncate_html method this would help. As part of that, writing a html_length_of function, along with validates_html_length_of would improve the action alerts handling related to issue #5695.
