~Changelog:
R1  (21-Aug-2005)
Lots of changes and additions. Now a full-blown Release version...


0.3 (20-Apr-2005)
Fixed '...' so it appears when expected; added 'all' argument to
allowedtags parameter (allows all HTML tags); altered filter_type
so if 'content' is the argument, WordPress text formatting occurs
(HTML paragraphs, 'fancy' punctuation, etc).


0.2 (16-Dec-2004)
Plugin now attempts to correct *broken* HTML tags (those allowed
through 'allowedtags') by using WP's balanceTags function.  This
is controlled through the 'fix_tags' parameter.
