Started to refactor the Events API stuff to work like the Talks API stuff, with a sprinkling of Redis in there
Added predis library
Home page and events listing pages work on Redis
Event detail page works, and started to make better use of the intermediate Db object
Map page is working
Schedule page works
Talk detail page works
Made the talks quicklink work
Shorter keys
New config
Made the user login work
Fixed the config object in a couple more places - only the search left to fix
Fixed the config object in the search
Removed the Mongo class
Reflect the switchover to Redis in the config
Removed the Redis DB index usage, and replaced it with Predis' implementation of a key prefix
Caught some more uses of the DB index
Had trouble getting the Predis auto-prefix to work, so I've implemented it in the Cache Service class instead (for now).
Clean up design for Talk page
Also included styling changes for comments and sidebar/short URL on the Events page too, and changes to the navigation/search on the main template
Merge branch 'master' into magicmonkey-redis2
