Modified build to work with maven 2
Modified so it will download monasca-common jars
from tarballs.openstack.org if the user is jenkins, otherwise the
user is told to build and install monasca-common
Had to move the source code to the new thresh directory so that a
separate module could do the download before dependencies would
be checked by maven
Had to explicitly set the project name in the control file, not sure
why
