Summary:
Bring Zune to level of MUI 3.8.

Required:

• Implement all MUI 3.8 features in Zune that are currently missing from Zune.
• Fix all Zune classes that do not function in the same way to their MUI 3.8 equivalents. Since this could be open-ended, only need to prove basic functionality is the same, don't need to track down every quirk.
• Amend Lunapaint to use your fixed Zune classes, so that it runs on both Zune and MUI3.8 without platform-specific changes to GUI code.

Optional:

• Port Zune to OS4 and MorphOS.
• If test code used to check required Zune functionality, releasing this code as a test suite for future use would be beneficial.
