Update jquery.kwicks.js

Type-O Close bracket - Update to handle % as unit and set px as default.
Additional adjustment to manage percentage-based width

Usage:
Optional new configuration setting: units: '%'    (default is 'px')
If selected, these settings have an alternative meaning:
size = size of container in pixels when displayed at 100%.
maxSize = width of image when expanded to display at 100%.
spacing = space between images as a percentage of 'size'.

From this, calculations determine the image size in the traditional sense to be used by the remainder of the function.  

Example for 300x200 images in a container with max-width = 950px:
size: 950,
maxSize: 300,
units: '%',
spacing: 0.3,
...

Result when displayed at full-width (ignoring spacing):
image maximum width = maxWidth (300px) / size (950px) = 31.6%
normal 'size' = container (100%) / no. image panels (6) = 16.4%
image minimum width = (container - maxWidth) / (panels - 1) = 13.3%

As container reduces in size, all image windows reduce proportionately.

Future enhancement - scale images maintaining aspect ratio (reduce height)
