Add primitive capsule

[rubenmoor]

I added AppendCapsuleMesh to add a primitive to any mesh with a capsule shape defined by

• Radius (of the hemispheres)
• CylinderLength (the length of the cylindric part)
• the mesh resolution
  • HemisphereSteps
  • CircleSteps
  • CylinderSteps

and a transform.

I have troubles getting the wrapping of the uv coordinates right, apart from that this works fine.

I use duplicate vertices at the poles and along the seam for the cylinder for the purpose of having a correct uv mapping.

Sorry for messing up all the tabs/spaces.
