Remove duplicate ports, add relevant lines to MOVED
devel/common_msgs renamed to devel/ros-common_msgs
math/geometry renamed to math/ros-geometry

- 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
- Sort pkg-plist
- Bump PORTREVISION

common_msgs contains messages that are widely used by other ROS packages.
These includes messages for actions (actionlib_msgs), diagnostics
(diagnostic_msgs), geometric primitives (geometry_msgs), robot navigation
(nav_msgs), and common sensors (sensor_msgs), such as laser range finders,
cameras, point clouds.
