Improved blog layout & design

I have now fixed a lot of my earlier bugs in the CSS script for the blog.
I also added some javascript code to import my del.icio.us links.

My blog now nearly conforms to valid CSS-3.0 and XHTML-1.0-STRICT, but not quite yet. Basically, it's because of some untraditional hacks in CSS for IE-bugs on float alignment, and also, the XHTML because of some bad syntax variables, but they are all contained in the widgets used in the sidebar, and I won't hastle to inform all the developers about it, simply because there are a few of them, and it doesn't bug me...

My revisions of the CSS and XHTML style template-files are valid, so, I'm happy ^_^
