Fixed stream template article CSS classes
* last article on a page has to contain the CSS classes "last" and "article"
** previously the position had to be manually increased by one because of some whitespace-only nodes
** due to the removal of indentation to enable code highlighting this manual increase is not only unneeded but prevented the correct classes from being set
Imported another batch of articles from my blog
* this should be the last one, as the remaining articles are not really worth preserving
** at least that is my current assessment
* updated contact page with actual content instead of filler text
