move ABS2ABS, ABS2GAL and ABS2Scenario to non-UI transformations plugins
The classes ABS2ABS, ABS2GAL and ABS2Scenario, doing the work of their respective handler, are in their respective UI plugin, since they rely on the file system, and are dependent on an Eclipse project structure.
However, they should be in the non-UI transformation plugin, to provide the API for the standalone version of the plugins. They should not depend on being executed in Eclipse too.
