Upgrade the Robot Operating System ports to their 1.4 aka Diamondback versions.
Detailed changelists are available on the WWW sites.

Port changes:
- distribution files are now fetched from upstream servers instead of
  using local copies from my server
- Python files are now always compiled (to .pyc and .pyo) and use Python 2.7
- devel/ros is now split in to devel/ros, devel/ros-documentation,
  devel/ros-rx, and devel-ros-comm to allow more lightweight installations
- Connect latter 3 ports to the build

Common code for working with images in ROS:

camera_calibration_parsers contains routines for reading and writing camera
calibration parameters.

image_transport should always be used to subscribe to and publish images. It
provides transparent support for transporting images in low-bandwidth
compressed formats. Examples (provided by separate plugin packages) include
JPEG/PNG compression and Theora streaming video.

polled_camera contains a service and C++ helper classes for implementing a
polled camera driver node and requesting images from it. The package is
currently for internal use as the API is still under development.
