WikiPageEntityLookup currently implements memc based caching. This should be factored out into a decorator implementation of EntityLookup that does memc caching.

In addition, we need an in-process caching decorator, so we do not have to load the same entity multiple times from memcached if it is e.g. used multiple times for resolving calls to the {{property}} parser function, etc.
