Components as taxonomy

[slaFFik]

Members, groups, forums, sites etc - they all should a separate custom taxonomy for one bp_feed new CPT.

All taxonomies will be registered through an API bpf_register_feed_component() etc. All taxonomies will be added to DB on registration (with avoiding duplications, of course).

End result:

1. BP Feeds top level menu
2. Components submenu which is custom taxonomy with a bpf_component slug
3. Every new extension (members, groups, events, forums etc) will register itsуда and that will add a new term record into db to this taxonomy.
4. On import every feed item will pass its component and that will assign term_taxonomy to each imported feed item. That will update counters in admin area, and will give ability to query easily.
