Initial commit

kure_base:
 - kurt_base.cc taken from kurt_chassi.cc (kurt software) with some
   extensions from the player version
 - speed-pwm-leerlauf-*, canpie/* taken from player-plugins
 - kurt2can.cc taken from player-plugins, added rotunit code
added third axis of the Cyborg Evo to limit the speed

added new parameter max_vel_x and max_rotational_vel to set a hard speed
limit.
rearrange launch and urdf files

general:
- components which have an own package have their urdf and launch files
  in the package (kurt_base, kurt_teleop). Composed robots and other
  parts have their urdf in the kurt_description and the launch files in
  the kurt_bringup packages (in accordence with the pr2 setup).

urdf:
- every robot is composed out of a base (indoor, outdoor) and
  different tops (kurt2, kurt360,..)
- tops are again composed out of different parts (sick_lms200,
  rotunit,...)
- generic xacro parameter should go into kurt_description/common.xacro
- complete robot urdfs should go into kurt_description/robots/
- kurt tops are in kurt_description/tops/
- other parts are in kurt_description/parts/

launch:
- typical robot setups can be launch from kurt_bringup/launch/
- launch scripts for packages imported from ros should are in
  kurt_bringup/launch/
- kurt_base: launch files for indoor, outdoor and fast kurt_bases
- kurt_teleop: cyborgevo and keyboard launch files
Bugfix wrong coordinate system

use angular.z instead of angular.x everywhere
