changing NSSlider values in the Inspector doesn't mark the interface dirty

[buzzdeee]

I recognized, when opening a .gorm file in Gorm, and the only things change are clicking an NSSlider and then changing some values in the corresponding NSSlider Inspector, the document is not marked dirty.
I have to move an object in the document around, or edit something else, to get the "Save" menu entry active.

This is with Gorm 1.3.1

this is still the case with Gorm 1.4.0
