ACT-119: added webservice dependencies to Tomcat /lib during demo.setup which fixes the blocking issue of having either a failing cxf module build or a broken Explorer.

ACT-19 still need to remove el-api from tomcat in demo-setup untill juel-engine el-resolving is fixed

Changed mapping and added database configuration. 
Added select, insert, update and delete method to CycleServiceXStreamImpl class and CycleService interface.
