function admin_block_get_cache_id in Admin 6.2

Implement our own simplified block caching. Because the Drupal core block caching system is so conservative (e.g. disabled when *any* node_access module is enabled), we roll our own solution here. Note that except for the introduction of a user 1 specific cache, the cid generated by this function is compatible with those in Drupal core.
