Default Value limits for 'continuous' type joints

[antbre]

When previewing an URDF with continuous type joints, by default, the control does not work since the default values of the limits take on all zero values. In the definition of continuous type joints the limit paramet is optional, therefore many URDFs with these kind of joints do not have the limit parameters set.

I suggest to set the default values to something like:

    <limit lower="-6.28" upper="6.26" effort="1000.0" velocity="1000.0"/>

to avoid this problem.

Thanks to your suggestions, you should now be able to drag the continuous joint directly on the 3D view. Your suggestions will be added in the next version (when I have time). Thanks
