Enabled authentication for governance.  Also updated the s-ramp
installer to properly configure JBoss for overlord security (e.g. SSO
for web apps, BASIC auth + proxy auth for s-ramp-server and
s-ramp-governance).  Updated the governance layer to make authenticated
calls to the s-ramp api.  Updated the JBPM console config to include
proper default values for making authenticated calls to the s-ramp api.
Use the released version of overlord commons.
Updated the build properties when the s-ramp installer is used within
the src tree.
