Use popular notice stream for favorited page

Use a caching stream for popular notice section
Instead of a big cached query, we now use a caching notice stream for
the popular notice section. It uses a single-table query at the
bottom, then scopes the notices and filters for silenced users. This
should be much nicer to our database servers.
Also clears the popular cache when someone favors or disfavors
something. A nice optimization would be to save the last weights and
re-calculate them at invalidation time, adding the new notice (or not)
depending on its own score. That will have to wait for another day,
though.

Let CachingNoticeStream users skip the ';last' optimization
This should resolve the issues darkip was reporting with user_im_prefs entries returning null immediately after insertion (seen with memcached off, so it was happening even with the built-in in-process cache in the Cache base class).
What was happening was that the initial pkeyGet() would end up saving a negative cache entry under the form with the fields sorted in the key, as via multicacheKey():
'statusnet:blaguette:user_im_prefs:screenname,transport:brionv,sms' => 'N;'
then we'd do an insert() on the new entry, saving cache entries for the non-sorted key names returned by _allCacheKeys():
'statusnet:blaguette:user_im_prefs:transport,screenname:sms,brionv' => 'O...'
'statusnet:blaguette:user_im_prefs:user_id,transport:1234,sms' => 'O...'
but the next query via pkeyGet() still saw the negative lookup cache from before, and came back with null.
Now, _allCacheKeys() sorts the fields in the keys by using the same key-builder function, and queries pick up the same thing you just inserted. :)
Memcached_DataObject doesn't quite fully understand unique indexes, and can't properly build cache keys for compound unique or primary keys.
Managed_DataObject has more information in its schema data, so we can build a proper list.

Issue #546: enable case-insensitive searching in MySQL
remove more groupnav
remove group nav
shorter title for tag cloud section on groups
remove group nav
move pending queue to sidebar
Move group logo edit from object nav to block actions
Show blocked users from group in section
MySQL needs the collation utf8_general_ci to support case-insensitive
searching. lib/mysqlschema.php already supports a 'collate' attribute on
a per-column basis, so we just need to take advantage of that attribute
on the columns we want to search and Bob (and BOB, and bOB) is your
uncle.

I was storing the full objects in the cache for the listGet()
function. I've changed it to store only pkeys, and use pivotGet() to
get all the corresponding values.
This also required changing pivotGet() so it can get objects with
multi-column pkeys, which complicated the whole thing quite a bit. But
it seems to work OK.
This method lets you get all the objects with a given variable key and
another set of "fixed" keys. A good example is getting all the avatars
for a notice list; the avatar size stays the same, but the IDs change.
Since it's very similar to multiGet(), I refactored that function to
use pivotGet().
And, yes, I realize these are kind of hard to follow.
