Developer release 0.4.01a

This latest version of fproc is a developer release, and intended only for 'playing around with', and so that users can see the direction that the project is going in.
I am currently in the process of switching to CSS formatting for all pages.
The code to unify client/user mimemail handling is not written yet, therefore 'templates/default_template_*_html.php' files are identical.
Please expect bugs in this release.
