PHPWidgets! 0.92 is released

The newest version of PHPWidgets is out, the code has been cleaned up, and security has been improved, this release prepares the way for diskcaching (have a browse of the CVS for the start of this). There are a handful of changes that need to be made to existing code (see the UPGRADE file)... the demo site has been updated with these changes.

The Template.inc update package (needed for sessions support and <!-- IF VAR --> blocks) has not been changed for this release.
