Updated to use new naoutil naming for files moved to naoutil. Added refresh-ext-projects.sh to automate bringing files from external projects (currently only naoutil) for ease of packaging and use in choreographe. Changed run-tests.sh to use nose as test runner if it is available.
Fixed bug generating ObstacleDetected events (was not wrapping sensor values in Sensors object). Updated to new version of naoutil. Implemented localized text lookup when executing Say action
