[ros-users] call for testing: camera1394 in C-turtle

Jack,  Looking carefully at Coriander, if absolute_capable is TRUE then 
it will DISPLAY absolute values (like real valued shutter speed instead 
of integers than mean little).  But it will only allow the user to EDIT 
(thus calling set_absolute_value) is abs_control is also TRUE.  On the 
XCD cameras, abs_control is FALSE.

A very simple fix makes this work correctly.
