Fixing issue with ModuleAutoloader on Windows

On Windows *ModuleAutoloader* can't load my module, `./module/MyModule.tar`, because GlobIterator returns an empty array for the path `./module/MyModule.*`. This issue is spoken of in this [SO](http://stackoverflow.com/questions/16396334/why-does-globiterator-produce-a-different-output-than-the-glob-function).

Strangely it just worked on my dev machine (a Mac) without this change. This change works on both my dev and test machine.
