Rework the include system to autmaticallly include *.inc files from a set of given directories in a theme. This will allow for use of the standard function calls that people are familiar with and still allow for breaking up of functionality into separate files.

Opt for using the CSS_SYSTEM constant instead of creating a new group for framework stylesheets. Then I give it an obnoxious weight.

Make the preprocess file functionality carry down to the subtheme.
Remove old preprocess file enabling code in base subthemes.
Remove unneeded template.php in Paint.

Remove remaining dpm() function in preprocess-comment.inc and unneeded span tag from page.tpl.php. Both files in the Canvas theme.
