Implement in r24696. There is now field name laundering by default (option in 
osmconf.ini)

There's also now a 'multilinestrings' layer that has relations with 
type='route' or 'multipolygon', and a 'other_relations' layer with relations 
that don't belong to the multipolygons or multilinestrings layers.
