Simplify Directory Structure

[drhamad]

I would really appreciate if the directory structure for SMF Gallery Pro could be simplified.  Currently, in addition to the files that are in the appropriate SMF directories, there's five base-level SMF Gallery Pro directories (highslide, js, images, css, gallery).  I would appreciate if these could be reduced to, at most, one.  This would simplify organization and duplication significantly.

Js, images, css were for lightbox support could proably move them to the gallery folder as well.

That would be appreciated, especially since they're not even identified as being related to gallery.
