[x] GUILayer removed from all sample Scenes
[x] Validated each scene in build (resolved some missing script references post upgrade)
*Note, UIVerticalScroller seems to have an issue, will address later.
Reviewed other samples and moved their code to the new "Examples" namespace
Minor fix on HSS/VSS to address issue where Next/Previous buttons didn't enable when new pages added to an empty control
Added new Circle class (example in LineRenderer scene)
Changed some of the LineRenderer public variables to public properties, else they are not assignable in the editor for events. Will check other controls as well.
