Rosmon not sourcing workspace when launching nodes

[aldoteran]

As the title says, using mon launch <package_name> <launchfile> as we do in the bringup scripts seems to ignore the sourced workspace and launches the launchfile from the same package installed using apt. No solution yet but a workaround is to either launch the file without rosmon or, alternatively, using mon launch <path to launch file> [arguments] as described in http://wiki.ros.org/rosmon.
