int_meta 6.x-1.0-beta3

#319739: Fatal Error - Fixed a problem where the D6 branch was not compatable with PHP 4.
#302976: comma separated lists of tags not created - Moved the checkboxes around in an effort to help people with a fixed-width theme.
#247542: Meta tags on the <front> /node page - Added basic support to also show Metatags when a node is rendered as a teaser.
Also removed the int_meta_types table in favor of using the variable functions.
