The rosversion command requires that the package.xml are available at
run time. The rosversion command is used when starting roscore.

In the topic-tools recipe, a QA error was raised as the .debug files were put
into the main package. By adding this line in the catkin class, the files are
now placed in the dbg package.

The CMake generate_messages function from the genmsg package
detects the installed message generators via files in the
/usr/etc/ros/genmsg directory. Stage the /usr/etc directory
manually as it is not a common path.

Fixed #50

Build catkin packages out of tree as this is the default of ros and
makes it simple to identify build paths.

Remove all ${BPN} file entries as catkin packages always use
underlines instead of hyphens.
