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
win32: py.path.local.sysfind(name) will preferrably return files with extensions so that if "X" and "X.bat" or "X.exe" is on the PATH, one of the latter two will be returned.

try to fix failures related to subversion 1.7.
