New tags from Denys added, load_to_mongo.py improved to handle base tags, index created, hotkey field added to Tags model, base tags displayed on main page, JS added to enable adding of those tags to tags box and make hotkeys work, bug with hotkeys on body fixed, layout for main page updated to add tags list. Review page updated to utilize bigger page width (5 shreds per row instead of 4 now)
