Skills and Categories now link correctly
a few minor changes to views (aesthetics/text), removed the pointless SkillTags entity which was making life awkwarder than I expected, entity now makes its own many to many table between skills and tags. Cv initializer changed so it now populates all of the tables with something with each relationship being used at least once. Little bit messy with objects inside of objects inside of objects but it works and its an initializor so whatever.
