changed the resource urls of deliverables and tasks to be more consistent with each other and the workpackages and with the general convention of having non-capitalized individual url names. updated the properties as well. the changes are in the java programs and their output ttl files so they are not active on the server yet, the ontowiki templates have to be updated as well. the resource url names are now wp<x> for workpackages (not changed), t<x>-<y> for tasks (from Task<x>-<y> and d<x>-<y>-<z> for deliverables (from D-<x>-<y>-<z>).
