Behdad Esfahbod
39dede9fff Make sure boolean features always use value=1 
Previously boolean features turned on the entire feature mask.  This is
wrong if feature is Alternate and user has provided values bigger than one.
Though, I don't think other engines support such corner cases.

852912fc2d Fix applying default-value for features 
Previously if a default global feature was overrided by a non-global
user feature, we were not setting any default mask for the feature,
essentially disabling the feature by default.  Fix that.
