Content search env compare

Introduced tag-soup (works better for my html download-and-parse function) and implemented two tests.

On the other hand, I seem to be getting lot of errorr regarding some of my fake-repos, in wein of

size_missmatch on http://inecas.fedorapeople.org/fakerepos/severity_zoo/fox-1.1-2.noarch.rpm

resulting in failed setup and skipped tests. Is it a problem in master as well? It should mean lots of skipped tests for "UI - Search Errata in Content Search"
