Refactored TestConfig creation for py.test based unit tests. The method used before had multiple problems: config creation did not use inheritance (as it does when used the wiki in production). It also didn't do the post processing done in __init__ of Config class. Also, it first created the request with some default config, then created the TestConfig (but some stuff in request was not initialized correctly)... The new method now uses config inheritance in the same way as a production wiki does. The TestConfig instance is created in RequestBase __init__, it does not use sys.path any more to import the test wikiconfig, but does an absolute import from MoinMoin._tests.wikiconfig. TODO: * fix the failing test_pysupport.TestImportExisting.testExisting * auth tests are currently skipped because they need more work * find a better way than staticmethod(TestConfig)

MoinMoin Testing Framework
--------------------------

All test modules must be named test_modulename to be included in the
test suite. If you are testing a package, name the test module
test_package_module.

Tests that need the current request, for example to create a page
instance, can refer to self.request. It is injected into all test case
classes by the framework.

Tests that require a certain configuration, like section_numbers = 1, must
use a TestConfig to create the required configuration before the test.
Deleting the TestConfig instance will restore the previous configuration.
