Started working on modeling of UAV using Blender.

So far, I have modeled the general flying wing and stabilizing endplates. Due to issues with using Blender's "extruded curve" function (in tangent twist mode), I cannot accurately model blended winglets. Hence, I had to settle for endplates instead. Hopefully these will act as vertical stabilizers while also reducing vortex-induced drag.
Added my customized Ardupilot build as a submodule.
