More minor updates and tweak.

While I am at a content creation dead-end, I am still working on this site. Real life as always takes precedence and I have not had a lot of time to create new content. However, I have continued to work on the site by tweaking the custom theme and adding a few modules.

Many of the tweaks come from my work on custom theming for my main client and have extended the usability of this theme to properly cope with situations where there are no side bars (like the 404 error page) or there are two side bars (not yet implemented). I ventured in to the PHP aspects of theming to change some of the default behavior of the Zen theme. Also, in testing the custom theming for my client, I have enabled some fixes for IE 6 compatibility.

I have also gotten some additional modules that allow enhancements to the site like adding icons to indicate external links (similar to those used in Wikipedia). Another module makes the breadcrumbs a the top of the content behave in a manner that is consistent with the structure of the site.

Hopefully, I will have an opportunity to get some new content release on this site, even if its just a new blog entry.
