[AD] update_dialog and MSG_IDLE

[Julien Cugnière <jcugniere@xxxxxxxxxx>]

When update_dialog broadcasts a MSG_IDLE, it sometimes checks the return 
value, and sometimes not. Vitaliy Maksimov posted a patch on [AL] to add the 
missing checks.

Here is a modified version (using "dialog->res |= ..." instead of "dialog->res 
= ...") which should be applied instead.
