- Rename *taskId methods to *task to reflect what they handle
- Remove usages of Wrapper where applicable
- Replace some uses of legacy Settings with NewSetting calls
- Abstract Messages into two layers: the top layer 'Messages' is how Messages can be retrieved and sent as before. In the background, package-private, MessagesManager actually does the file read and worries about I/O while Messages takes care of higher-level things (such as joining two lines or checking the current language).
Replaced many classes to use Wrapper to get singletons and replaced the test setups to use the WrapperMock instead of setting fields through reflection
