Update for iCubHeidelberg01 configuration files

Two things related to iCubHeidelberg01, the first commit is for properly installing camera configuration files and to add a robotMotorGui.ini file.

The second one is the initial experimental commit of wholeBodyInterface related configuration files. At the moment this software is not part of the icub-main repository, but given that this files are highly robot dependent I already discussed with @lornat75 that it could make sense to have them in the `app/robots`
 directories together with all other configuration files. 
The added files are : 
 * `wholeBodyInterface.ini` generic configuration file for using the wholeBodyInterface based software (and thus https://github.com/robotology-playground/WBI-Toolbox ) on that robot 
 * `model.urdf` initial draft of the urdf model of the iCub, using the naming conventions explained in https://github.com/robotology/icub-main/issues/57 . This file contains the geometric and inertial parameters of the robots used by the wholeBodyDynamicsTree module. 
 * `wholeBodyDynamicsTree.ini` configuration file for wholeBodyDynamicsTree module, that then depends on `model.urdf` and  `wholeBodyInterface.ini`.
