IsdialogMessage16 patch

[Rein Klazes <rklazes@xxxxxxxxx>]

Hi,

This commit: http://cvs.winehq.com/patch.py?id=1025828582516861871424229
changed IsdialogMessage16 sufficiently to break mouse message handling
in WordStar for Windows V2.

This patch is sufficient to make it happy again.

Changelog:
	dlls/user	: msg16.c
	IsdialogMessage16 must not process messages that are not
	intended for the dialog box.

Rein.
