#569 Add themes with larger font sizes

[ColoredPixels]

Simple: Please add a few themes with larger font
sizes. Old folks have poor eye site. That is almost
guarenteed. So, clone a few of the themes, and
increase the font size by +25% and +50%. It can be
done by editing the font-size in style.css and the box
sizes in theme.php.

The themes specifically ignore the IE->view->Text Size-
>Larger that a user who needs help would have set.

Getting and incorporating the code from http://www.
familyinfo.us/familytree/pedigree.php for dynamic font
handling would be wonderful. See http://www.
familyinfo.us/?Do=page_control for more details.
