1.4.18
fix test collision
remove trailing whitespace everywhere
move test files out of py lib proper * separate all tests from plugins * simplify implicit inclusion of plugins under test * have test_initpkg perform direct checks instead of yielding tests * fix example tests for 3k
don't depend on (and don't actually use anymore) testing/__init__.py
simplify chdir handling in tests
fix internal test, thanks thm
try to fix failures related to subversion 1.7.
