OF-859: Pubsub fix; misc cleanup

This fixes a problem with a static final reference in the Node.class. It
also addresses a couple of minor issues discovered during pubsub
testing:
- PubSubPersistenceManager should return an editable collection rather
than a read-only collection for published items
- SequenceManager defaults should use a blocksize of 5 for frequently
used tables
- LocaleUtils should catch and log a MissingResourceException and return
the key in lieu of the missing value (by convention)

OF-860: Self-presence is not broadcast if room has more than one occupant.

The problem here was, that the presence's 'to' attribute was overridden on each iteration, making the if statement fail after the first iteration.
