1. Moved some images to resources/images where they belong (so they won't
be served by the request processor and subjected to perm checks).
2. Removed gifs. "live.gif" and "golive.gif" weren't used any more (probably
because images with embedded english words are forbidden). The file and
folder icons are now grabbed from the file storage package.
3. Changed the files referencing the old directories.
There are a ton of images in the delivery engine. Rather than move them
to a standard place, this package may want to implement a custom filter
to deliver them before the request processor gets ahold of them. Assuming
people want LORS course delivery to scale well ...
