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

- Use WRKSRC instead of WRKDIR in the MAKE environment to point to the
  build directory
- No need to make scripts in */src/* executable
- Don't move libraries to PREFIX/lib but symlink them there, some Python
  modules depend on the libraries in their original location
- Add WWW line to pkg-descr
- Bump PORTREVISION

This stack contains tools built on top of ROS core which are commonly used
throughout the ROS ecosystem. It contains three types of packages:

Filtering:
* bfl: the Bayesian Filtering Library from the Orocos project
* filters: a standardized C++ API for filters. It also has a class to chain
  filters at runtime based on parameters.

Helper libraries:
* actionlib: provides C++ and Python libraries for interacting with the Action
  API used by the executive.
* nodelet: a way to run multiple algorithms within the same process abstracted
  with a ROS interface.
* pluginlib: providea a C++ API for dynamically loading plugin classes.

Parsers:
* tinyxml: a C interface to the third-party tinyxml parser for ROS.
* xacro: an XML macro language.
* yaml_cpp: a C++ to the third-party YAML parser for ROS.
