Focused on optimizing caches. There are now two caches, local and remote (memcached) for the sake of getting page-caching to work.

Added: Scale to seeds file, to produce varying levels of data.
Added: Caching module with remote cache (this is memcached)
Changed: Default cache to memory store (this is the local cache)
Changed: Models (Video, VideoPolicy) now write out to the remote cache.
Changed: Page caching is now performed in the local cache.
