Added new integration folder to allow Selenium testing on alfresco-amp.
Share-amp and the all in one amp, now also have the share-po project which will allow selenium testing and regression testing using alfresco test library. It also enables users to write and extend the page objects and write tests for their customisation.

Sample command:
mvn install -Pamp-to-war,functional 

On share-amp and all in one:
mvn install -Pfunctional,regression
