Remove all of the mock test files since that wasn't a good way to
do mocks for tests.  The spring injected mocks will be replaced by
a mocking framework later.
Remove validator references and entitymanager references.  Replace
these with a hibernate core reference.  Change the spring security
reference to a milestone release to get the new java config stuff.
Remove integration-test files.  Move userdao tests to the regular
test area.
