message.c patch

[michael cardenas]

Here's another small patch, written by Phil Landman (one of our
programmers) for PeekMessage that solves the problem of winelib apps
taking 99% of the cpu when they're idle. It's just a counter that waits
a little bit if we haven't recieved any messages in a while. You'll
see... Anyway, it works well, we only use 5% when we're in the background.

I'm going to have to give you guys little bits as I come across them.
I'm still working on fixing some of the bugs introduced in canvas when I
picked up the latest wine. So, I'm trying to get beta3 out the door...
