At the moment, our testing story can't use things like 'tests_require',
etc., because they are only known at the time 'setup()' runs.
eggtestinfo addresses this problem by writing introspectable metadata
into the "egg info" directory:  this information derives from the
various testing-related arguments passed to 'setup()'.

I worked some on getting ZODB / transaction etc. to run at least most of
their tests from 'setup.py test' (those which don't require layer
setup).  The last example shows the metadata from a package which uses
the new 'test_loader' I wrote for this purpose.

I also added another setuptools plugin to 'zope.testing', to allow
running all tests via 'setup.py ftests'.

Somebody likely needs to extend zc.buildout (or a recipe?) to use the
information generated by 'eggtestinfo' when building testrunner scripts.
 My zc.buildout-fu is pretty weak at this point :(.
