*Don't show icon when object picker is empty:*

When an object picker is empty, the label reads: *None (Type-of-object, eg Texture 2D / Material)*
* Because type of object is stated in the label, there is no need for the type icon to be shown when obj picker is empty,
* Showing an icon when obj picker is empty creates confusion as reported by users, perceived as there is a texture there named missing

*"Empty" text styling*
* A while back design team proposed a text-style for *"empty menu / none available / place holder"* texts. We recommend this style used for None / Missing when obj picker is empty.
* This text style is intended for n/a or empty controls. It uses 70% alpha. (as opposed to 40% in disabled style).
