Support Multiple Value imagefields

Hi all,

Introduction
Piclens/cooliris slideshows were not showing all of the images in a Multiple Value imagefield, only the first image per node.

This patch has been used in the following configuration:

Modules:
-CCK with imagefield
-Views
-ImageCache

Setup:
-Multiple content types using the same imagefield (Image)
-'Image' imagefield is set to accept Multiple Values
-Set up a Grid (from the Views Bonus Pack) type View page with the fields:
-- Node: Title and
-- Image imagefield (with a Lightbox2 option)
-Set a MediaRSS: RSS Feed Selector (Display All values) argument
-Set the options under MediaRSS/PicLens Fieldset to:
-- Image field: Image
-- Preset for thumbnail: Thumbnail (imagecache preset)
-- Preset for content: Large_Image (imagecache preset)

Solution
Modify the piclens_views_mediarss_items($args) function within piclens_views.module, specifically under the else statement at line 167. This required reorganisation of some of the other code, which may effect configurations using Image node types.

I am not a strong coder - there is a bit of code redundancy, so this needs review and/or work.

I hope this is helpful!
Cheers
