Added the testee configuration variable and the config.nativize_path function The testee configuration variable stores the string or iterable of strings to pass to subprocess.Popen except that the first/only string always follows the POSIX pathname format or, if the native format is really needed, is prefixed by slash-slash-colon (the same format is used in Boost.Filesystem). config.nativize_path is now a part of the public API of the config module. It converts a path in the format described above into the native format and can be used in testconf if it needs to use paths other than testee[0].
