- express most of the orm.util functions in terms of the inspection system

- modify inspection system:
	1. raise a new exception for any case where the inspection
        context can't be returned.  this supersedes the "not mapped"
        errors.
        2. don't configure mappers on a mapper inspection.  this allows
        the inspectors to be used during mapper config time.  instead,
        the mapper configures on "with_polymorphic_selectable" now,
        which is needed for all queries
- add a bunch of new "is_XYZ" attributes to inspectors
- finish making the name change of "compile" -> "configure", for some reason
this was only done partially
