Introduced changes from https://github.com/rtv/Stage/issues/34 with some changes (does not require lasers to be present and works without cameras).
Added RGB+3D-sensor interface (Primesense/Kinect/Xtion).
 * Publishes CameraInfo, depth image, RGBA image, tf (takes world-file pantilt paremeter into account)
 * Supports the "old" configuration (laser+odom) as well as camera+odom, laser+camera+odom and odom-only.

Fixed laser transform height (previously was hardcoded at 0.15, now it takes robot height into account).

Ground truth pose screwed-up coord system?

I remove the hack that claims that it fix Stage's screwed-up coord system. But in fact is that hack that makes the ground truth wrong, so I need to amend in my app.
Maybe the hack used to fix something that has been lately fixed in the underlying stagelib. Or maybe I just misunderstood the problem.... feel free to just reject this pull request in that case.
Fixed tf (yaw component) for the base_link->camera transform.
