Added the topic and user memory caches. Currently used in an extremely limited way, we plan to expand this!

Added a template minifier which strips out many types of whitespace.
Stop the router from blocking the other goroutines.
Content is no longer an interface{} in the TopicUser and Reply structs
Allow plugins to add new routes without any potential race coditions occuring
Use non-breaking spaces in the topic view to make it harder for the minifier to break things.
