CCK - Configure Commotion page updated for 1.1

These are the basic changes, as indicated in Issue #250. There are still some other changes to make, but many graphics were also updated. I was able to take new screenshots for the first half of the page. All graphics should be proper resolutions through "Changing the Administrator password" (inclusive). Many of the images afterwards look okay, they appear to be 600px wide which is larger than the CCK container anyways.

@dismantl @critzo @natmey - Please take a look and merge when ready, thanks!
