robofsm: Preliminary version of sick-day application.

This is almost copy of demo application.

After power-up it waits for start signal.

After start signal:

1. Uses shape_detect lib for target detection from hokuyo data.
2. Turns on the same point by 120deg and detect - max. three times.
3. When no detection - generates new random point max 2 meters far.
4. TODO - On detection - approach the target.
	- Find cross-section point between path to the point and circle of some radius around the target.
	- Map handling needs lots of changes and improvements.
	  Actual type of map handling is not suitable for large spaces.
