Port Body and CapsuleBody classes to Kitelab 2.07.

  * Body and CapsuleBody classes are renamed to BodyDistance and
    CapsuleBodyDistance respectively.
  * BodyDistance no longer inherits from CkwsKCDBody. BodyDistance now
    holds a CkwsKCDBodyAdvanced shared pointer as private attribute.
  * BodyDistance constructor now takes a body shared pointer and a
    string as arguments
  * CapsuleBodyDistance is still a daughter class of BodyDistance.
  * Body factory classes are no longer necessary.
  * The Device class now holds all BodyDistance objects associated with
    bodies in a vector private attribute. The vector can be accessed
    with a public getter.
