Build script to run webtests and generate scenarioo documentation

[adiherzog]

As a developer of the scenarioo-selenium-demo and as a course pariticipant playing with this example I want to have a simple script I can start to run the UI tests together with docu generation and finally deploying this generated docu (including the refresh service call) to the scenarioo web app.

Acceptance criterias

• There is a simple script to use to run all UI tests including generation of scenarioo
• a new directory for the build is created inside which the docu is written
• build.xml is also created inside this directory.
• servcie call to import the build inside local running scenarioo webapp is triggered

This issue was originally scenarioo/scenarioo#258 which was moved here.
