Patch to get SmartForms running (fixes bug 575?)

[Joshua Thielen]

This patch fixes the problem reported running SmartForms in bug 575 
(http://bugs.codeweavers.com/show_bug.cgi?id=575). It also gets 
LogicWorks running (and probably any other 16-bit app that uses the 
SmartHeap memory management library).

It turns out, SmartForms does not need NotifyRegister implemented to run 
(so far, at least). The problem is that when WaitMessage16 was called, 
it did not yield control to the other 16-bit threads. This patch fixes 
this problem in WaitMessage16.

Modified Files:
wine/dlls/user/user.exe.spec
wine/dlls/user/msg16.c

Change Log:
Separated WaitMessage16 from WaitMessage and modified it to yield 
control to other 16-bit threads.
