[PATCH] 469557 - the required media dialog is HUUUUUUUGE

[Chris Lumens <clumens redhat com>]

If you're crazy enough to make a split media set for Everything, you end
up with a dump truck full of CDs.  That makes the required media dialog
rather large - so large it goes right off the screen.

Instead of doing anything clever, this patch uses the power of grammar
to reword the dialog and fit it in less space.
