Bug 9680 - cart aligned right in CCSR

The CCSR theme sets a min-width of 1000px for windows which are more
than 700px wide. This caused the cart popup window to be given a
min-width of 1000px, resulting in a broken layout with unnecessary
horizontal scrolling.

This patch adds a class to the cart template and to other pop-up window
templates to ensure that a large min-width is not enforced and to give
consistent padding to those pages.

To test, set your theme to 'CCSR' and view the following pop-up pages:

- The Cart. From the cart, trigger:
  - The "send" window
  - The "download" window
- From a view of a List's contents trigger:
 - The "send" window"
 - The "download" window

Each of these pages should look correct with no horizontal scrolling.
