Changes since DRUPAL-5--1-1:

• jQuery version of lightbox2 module
• renamed lightbox2 system variable - lightbox2_plus has now become lightbox2_lite
• Updated the path to the css files as they have now moved into a "css/" directory within the lightbox2 module directory. The layout of the admin screen has been altered and javascript is loaded to enable / disable form elements depending on
  what is checked. The "lightbox2_plus" system variable has been renamed to "lightbox2_lite" and the code updated accordingly. The term "lightbox2 plus" has been removed from all user visible elements on the admin screen.
