removed adjustments to LD_LIBRARY_PATH (forgot why, bad), and fixed the way it tries to figure out the version to assure it deals with non-standard installation
improved error logging
Made with_scene capable of dealing with absolute paths, which is when it sholdn't do anything
Improved wtih_scene to support a debug mode that doesn't do a scene.new
Improved path handling when trying to obtain the maya path. Its less specific and just parses the version out of any path, which should work just fine everywhere
