Remove subcamera and change drag point layer

Subcamera was only used to render objects on the NGUI Layer (8), which
only the drag points and NGUI stuff reside.

This fixes drag points position being distorted when the main
camera's FOV changes.

This also prevents NGUI things from showing up in the world.
