doc/londiste3: catch up with recent "compare --count-only" commit
londiste: create_partition now sets owner to match parent table
londiste: imported drop_obsolete_partitions(2) function
londiste: reformatted drop_obsolete_partitions() to lower case
londiste.drop_obsolete_partitions: added support for different partitioning periods
londiste.drop_obsolete_partitions: amended
londiste.drop_obsolete_partitions: changed to raise notice instead of returning rows; defaults to public schema.
noise
londiste: added dispatch handler arg retention_period

It controls how long to keep partitions around. Examples: '3 months', '1 year'
londiste.drop_obsolete_partitions: reformatted
londiste.create_partition: properly quote owner in ddl
londiste.drop_obsolete_partitions: changed back to return (and log) names of dropped tables
londiste: moved drop_obsolete_partitions() call to check_part()

Note that current behaviour is that dispatcher would crash if events older than retention period arrived.
Perhaps it is better than quietly recreating and redropping tables for too old events..?
londiste: sweeping change to postpone log string formatting
