Remove redunandant 'scripts' folder
Added redeploy options that allow this:
   mvn tomcat7:redeploy -DskipTests  -Dbm.tomcat.ip=54.74.38.161
   -Dbm.tomcat.port=9080 -Dbm.tomcat.server=remote-bmserver
Define 'remote-bmserver' in .m2/settings.xml with a username/password for
accessing the Tomcat manager application.
Fix callbacks when application is redeployed.
The application context used should not have been refreshed before giving
it to the ServletContext.  See javadoc of ContextLoaderListener(WebApplicationContext
context).
