Issue#233

- implemented all more actions in MyProgramsViewController, ProgramTableViewController, LookTableViewController and SoundTableViewController
- refactor alert views

NOTE:
* the copy object action in the ProgramTableViewController (More -> Copy) does not work correctly at the moment
* all other more actions (also the ones in other ViewControllers) only work until the ProgramTableViewController is left by the user

These two remaining issues only occur because the functionality depends on the serialization mechanism which has not been fully implemented at this stage.
