himuesgallery 6.x-1.6

Version 1.6
-----------
- Due to a hint from brodiebrodie i get knowledge of the module Colorbox. Because it is relativly simply
to implement is decide to do it ;-)
If Colorbox is enabled, himuesgallery will use it automatically.
I decide to implement the neccessary JavaScript-code in himuesgallery.tpl.php.
If you want to theme a module, this is the file in wich you do it. If you want to set other parameters for
colorbox, then you can do it in the same place.

Please notice that you have to use the colorbox modul and minimum jQuery Update 6.x-2.0-alpha1.

- eliminate the use of imageinterlace() to improve the thumbnail quality
