[rules-users] Drools flow web console (5.1.M1) deployment in JBoss

I just build from trunk usually, but the M1 version should be fine.

The error "Could not connect to task client" is probably caused by the
fact that you did not set up a task service (you need one if you want to
use human tasks)?  Check out
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch.Human_Tasks.html#d0e2117

Not sure about that second error, but let me know if that is still there
if you have the task service running.
