Add samplerobot-sequence-player and samplerobot-collision-detector

Add samplerobot-sequence-player and samplerobot-collision-detector which are ROS-user wrapper of hrpsys-base samples.

In the near future, hrpsys will merged to hrpsys-base and these samples can be moved to hrpsys-base[1].
But currently I added these examples here.
