Hastymail 1.0 Stable Released

This is the first stable release of Hastymail2. A lot of testing and
feedback has resulted in many bug fixes and improvements in all areas
of the core code. Several plugins have been updated with new features
and fixes, and 5 new ones have been added: username, saved_search,
custom_reply_to, login_alias, and pop_fetch. Supporting software like
tinyMCE and Soundmanager2 have been updated to newer versions, and the HTML content filter has been depracted in favor of htmLawed. The interface has been optimized to have fewer HTTP requests, better caching, improved theme CSS, and W3C valid XHTML.
