3D View - Object Header - Double "Copy Modifiers" and "Copy Modifiers to Selected"

[Draise14]

We got a double operator that does the same thing. I like the exposure of copying modifiers in the modifier menu..... but one should go.

The link menu could do without a "copy" entry, since linking modifiers doesn't actually link, but copy.

• UI: Add Modifiers submenu to 3D view header

Add a menu similar to the "Object > Constraints" menu that allows adding,
copying, and clearing modifiers. The "copy all modifiers to selected" and
"clear modifiers" operators are new, to mirror the functionality we already
have for constraints.

The "Add" menu is the same that's used in the property editor. In the 3D
view, modifiers are always added to all selected objects.
