Implemented build and run script according to the new CB specifications: …
    https://issues.apache.org/jira/browse/CB-2927
    https://issues.apache.org/jira/browse/CB-2939
Also:
1. Moved the debug token feature from "build" script to "run" script
2. Added a validation feature for debug token so it won't be created all the time
3. added --no-build and --keystorepass for "run" script
4. added a default build.id in config.xml
5. cleaned up output messages
