Added support for a list view to complement the grid view.  Right-clicking on the page rapidly switches between the two views.

The most recent view is saved in a cookie.

Added a Take column to the Feed table, this is is to specify how many entries to take for each feed.

Updated the background image again.  To something more suitable for scrolling down a list view.
