Added 'Crawer' to steal and fill our database with sample jokes. Crawer will only work on empty DB(having no categories) and having at least 1 user. 153 jokes added with 27 categories and 1610 tags (5439 joke-tag connections).
Removed hardcoded jokes as text files - everything happens in the memory now (needs internet)
