[#1621] Composite keys for resources

This patch implements the fundamental pieces of the move to composite
keys:
    * Instead of having a single namevar, we have a non-empty collection
      of them, and two resources are the same if and only if all of them
      match.  Note that the present situation is a special case of this,
      where the collection always has exactly one member.
    * As currently, namevar is determined by the type.
    * Instead just of inferring the single namevar from the title we let
      types decompose the title into values for several (perhaps all) of
      the namevar components; note that the present situation is again a
      special case of this.
