Felix Arntz 90c424f73b Multisite: Improve performance by caching not found lookups for sites and networks. ...

With this change, the result of a site or network lookup by ID will be cached even if the ID does not exist. When a new site or network is created, the cache for the respective new ID is cleared.

Props mnelson4, nielsdeblaauw.
