Testing/custom_zodb.py: added support use a different storage other

than DemoStorage. A dedicated FileStorage can be mount by setting the
$TEST_FILESTORAGE environment variable to a custom Data.fs file.  A 
ZEO server can be configured using the $TEST_ZEO_HOST and 
$TEST_ZEO_PORT environment variables. This new functionality allows us
to use the standard Zope testrunner for writing and running tests
against existing Zope installations.
