Element restructuring. Add support for new basic Element types including the RS objects and vectors(2-4). In theory this paves the way for maintaining type info for RS objects, passing elements for GLSL uiforms/attribs/varyings, and supporting nested structures.
This will break some apps, checkings for other projects will follow to unbreak them.
