Masterview devel - Oct 2006 - Directive metadata config rework, unit tests overhaul committed

Finally found what was causing the problem with directive resolution when
running the entire test suite as a whole, so committed all the code changes.
There''s still a bunch of trashy code and leftover debugging/tracing
hooks
from my attempts to track down the timing/loading problems; eventually that
should be cleaned up, but for the short term I''d like to keep that
around
just in case some other problem with this rework shows up.

I''ve got a little more cleanup and polishing to do in some of the
directive
classes and unit tests, plus some final additions to the docs, but I
think/hope this should wrap up the bulk of this work.  Finally!!
