week-4-assignment-3 done
fixed comment
Incorporated various suggestions for improvement.
- Used centralized handling of platform type, avoiding duplications of
"The Android Project" magic String

- Removed PlatformStrategyFactory, as it anyway was not used
consistently, and as the strategy depends on the input types.

Cleanup of platform handling
Merged improvements to the skeletons.
Added week-6-assignment-5 skeletons.
Force adding project.properties.
