Pom fixes and refactoring, Update to GB 1.4

in order to create the geobatch war:

* in the home folder of the repo type **cd main/geobatch**
* then run **mvn clean install -DskipTests=true**

for the Intersection Engine GUI:

* in the home folder of the repo type **cd main/ie**
* then run **mvn clean install -DskipTests=true**

then get the two war from the .m2 repo and deploy in one single Servlet Container (or two different if you want)

The applications has been tested on Tomcat6 and Tomcat7. A problem still occurs using Jetty, but it is only related to GeoBatch GUI, so the system can be used also on jetty.

Maven2 is needed for a succesfull build.
