Subject: [PATCH] Updated formula for xu4 (Ultima 4 engine)

It's a lost cause trying to get 1.0beta3 compiling under Snow Leopard,
and the trunk already compiles 64-bit clean, so we might as well
use that.

Note that the DATA patch makes a few changes that are then rewritten
by inreplace. Why not patch clean and not run inreplace later? Because
I'm going to submit the patch back upstream, which should hopefully
allow us to drop it from the formula and only use inreplace to select
our build environment (native arch and framework for either 10.5 or 10.6)
