Issue#233

- implemented all more actions in MyProgramsViewController, ProgramTableViewController, LookTableViewController and SoundTableViewController
- refactor alert views

NOTE:
* copy object action in 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 serialization mechanism which is not fully implemented at this stage.
