turtlebot_calibration perpetually waits for scan

[kbogert]

The turtlebot calibration script seems to go in an endless loop saying "waiting for scan", kinect laser is never activated.

I fixed it by replacing the 3dsensor.launch include in turtlebot_calibration/launch/calibrate.launch with the corresponding include located in turtlebot_navigation/launch/amcl_demo.launch

  <include file="$(find turtlebot_bringup)/launch/3dsensor.launch">
    <arg name="rgb_processing" value="false" />
    <arg name="depth_registration" value="false" />
    <arg name="depth_processing" value="false" />

    <!-- We must specify an absolute topic name because if not it will be prefixed by "$(arg camera)".
         Probably is a bug in the nodelet manager: https://github.com/ros/nodelet_core/issues/7 --> 
    <arg name="scan_topic" value="/scan" />
  </include>

Seems to be due to the scan topic name, but I'm not sure.

This was fixed with merge of #83
