SimpleViewer + image_gallery new integration module

attached code brings in a new module to display an image gallery through simpleviewer, will takeover the default display from image gallery
code should be safe, but backup, backup, backup and dont use on a live site because i just didnt got around to test it much, consider early alpha

there is another module for this http://drupal.org/node/241384 from flash_gallery but personally i dont like how it duplicates on the image gallery code, i do duplicate as well but less code, and my goal is to eliminate this through a patch to provide a better display hook in image gallery
im also looking for benefits to going through swfobject simpleviewer (would be easy to integrate), as an _added option_ to direct integration

it doesnt adhere to drupal coding style, if enough interest in this to make it into the CVS, ill modify and also remove the simpleviewer code from the module (which is now there for your convenience)

please leave comments on the code functionality, test & review, ill also answer any questions you might have related.. also bear in mind im not an experienced drupal programmer :-)

besides the admin page introduced, settings from image gallery itself affect its output (most likely youll want to up the images per page setting to something higher to not get the drupal pager below simpleviewer, note that simpleviewer doesnt recommend more than 50)
you will also want to tweak the fixed width/height settings as the auto width/height might be too big (even though i think i calculate this correctly), set width to 100% and test browser resizing with your theme
