[PATCH] ui/kis_dlg_adjustment_layer.{cc, h}: don't enable OK button if no filter is selected (avoid crash)

[Melchior FRANZ]

Don't enable the OK button in the constructor only because there's
a layer name given. At this point there's never a filter selected,
so we get a crash on clicking OK. Also don't enable the button if
the layer name was edited to be empty.

OK to commit?

m.


PS: I'll send another patch for automatically using the filter
    names once this crash here got fixed.
