git rm -r Prey

Prey hasn't been configured in a long time and last time I checked, it was
 broken.
git rm -r articles/

There are no sane articles in there.
git rm Asperger*.

Horribly ouddated and I don't feel like updating it soon. I will consider it
 when I am hosting somewhere else.
git rm index.fi*

There is no reason to support Finnish.
git rm the following:

	deleted:    HTML.html
	deleted:    Trans.html.md
	deleted:    mirrors.html
	deleted:    mirrors.html.md
	deleted:    topposting.html
git rm -r conf/ etc/

What is the purpouse of them?
I think everything is removed now. Closes #27.
404 & index: update.
Fix files.
Closes most of issues.
