Corrected wrong indentation in aggregator.tests
Refactured a bit and added removal of elements at the end of the article whose id or class contains a term from a list of keywords. Also added check if the extracted element is in our negative keyword list and if so, we start extraction once again with min_text_length set to 0.
Moved negative_keywords and metadata terms from artex and artex.Article to settings as ARTEX_NEGATIVE_KEYWORDS and ARTEX_METADATA_TERMS.
Added article extraction to documentation.
Added LiveTicker concept to the documentation. Feel free to comment and critisize.
Added Bookmark concept to documentation. Again: feel free to comment & critique
Modified aggregator/feeditem and importedarticle so that it now states where an feeditem's html is stored (in ImportedArticle, as is our current plan).
Merge branch 'master' of github.com:bericht/bericht
