Fixed now in SVN. Uses the base frame ID (after the last slash) as the
camera name. That seems reasonable. May be overridden in
CameraInfoManager if the calibration file returns a camera name.

No messy poking around with the node name for CameraInfoManager any more.

Frame ID is now resolved correctly using tf_prefix (adding a dependency on tf).

The driver node name still does affect the published topic names. Need
more study to determine what to do instead.
