Fix deployment problem...

When deployed with https://gitlab.esss.lu.se/nice/guis/ansible/ics-ans-wp12-opi.git, interface macros are not defined in macros.xml file. Fair enough...

However, the source code is reeeally deployment-dependent: file = os.path.join(directory, "../../../../mainDisplays/{}/scripts/devices.xml".format(chopper_area))

There should be a better way to make this, but for now this solves the problem.
