Item price column was the only column in the cart table without class
attributes.  Added class attributes to allow cart styling of the column
in the same manner that other columns can be styled.  

Removed a couple of extra spaces.

Issue #150
Unde previous (premature) commit
As discussed in #153

My suggestion is leave the 'wpsc_save_cart_item' action alone so we
don't break anything ,deprecate it.

Add a do_action('wpsc_before_save_cart_item', $cart_id, $this ) call
before the cart item record and cart meta is stored into the DB.

Add a do_action('wpsc_after_save_cart_item', $cart_id, $this ) call
after the cart item record and cart meta is stored into the DB.

jQuery 'load' not firing, need to use 'ready' instead

'get_cart' action was never being executed because the jquery 'load'
event would never fire.  This caused the 'loading...' message to remain
on the cart whenever caching is enabled.  The 'load' event was used for
other actions also, these were also changed to use 'ready'
Added missing semi-colon
