Changeset 7918 for trunk/bp-blogs/bp-blogs-cache.php

Message:

Pre-fetch blogmeta when in blog loops

This reduces overhead when querying for blog meta in the context of a
bp_has_blogs() template loop. Mirrors similar functionality in the activity,
groups, and xprofile components.

Also introduces an update_meta_cache parameter to the bp_has_blogs() stack, so
that plugin/theme authors can disable this pre-fetching.

Fixes #5398
