ZVISION: Draw transparent text in original save dialog

Before this change, text was drawn in black boxes in Zork Nemesis,
so while this does make it look better (and more like the original)
this may actually make the text slightly harder to read. The
original dialogs allowed only upper-case letters, but I think that
it's better to leave that to the player.
