another major codes rewrite: - created BaseRepo controller for all repo specific controller, and added common data propagation - removed obosete codes, and made optimizations, removed to often calls to RepoModel - fixed found bugs in files controller that generated unhandled 500 errors - cache issues - removed repo_branches global template values - journal fixes - main repo list is fully dict now it's less resource heavy that way
