Changed UI/forms to no longer render to an offscreen framebuffer.
By default all draw calls for UI (forms, controls, text) is now batched (it was never batched at all in the past).
Added a new property to form files called "batchEnabled" to allow disabling batching in rare cases where forms contain multiple transparent layers of controls and text in such a way that batching causes visual artifacts. For most forms, this will never be an issue.
