* python sys.cleanpath() used strstr incorrectly, resulting in paths containing a slash, always returning a path that ends with a slash.

* python Blender.GetPaths() - absolute=0 wasnt working
* BLI_cleanup_file and BLI_cleanup_file were treating the // prefix as a duplicate path, now ignores //
* BLI_convertstringcode was removing the trailing slash from a path
(tested these path functions didnt mess up with some of the peach files and with pointcache)
