OBJ Import should now meet up to the python standards

Browse Source 
http://mediawiki.blender.org/index.php/ScriptDev/Guidelines

* Recursive search was enabled by default, if your OBJ happened to be at root path, loading the OBJ could take ages. Made recursive searching optional.
* MAX's MTL exporter replaces spaces with underscores, image loading checks for this and loads the name with spaces if the one with underscores dosnt exist. not realy a problem with the importer but annoying to manually replace lots of images.
