Add more conductor tests, and tests for Execute, PropertyChangedBase
Attempt to change Deactivate(true) to Close()

Probably needs a bit more testing and verifying, but the tests pass
Tidy up / fix the conductors a bit more
Work on screens: tidying, bug-fixing
Add IChildDelegate so children can request a close of themselves off their parent conductor

With this in mind, reword the WindowManager and Screen.TryClose
Use SetAndNotify in example
Add ConductorNavigating, OnInitialActivate, and the StretchingTreeView. Not sure if the latter will stay
Add RedditBrowser sample
Move StretchingTreeView into RedditBrowser, and remove codebehinds
Start writing unit tests for Screen
Finish off the screen unit tests
Add some doc to IoC
Start on unit testing WindowManager, but there's not a lot I can do since Window is so hard to mock
Start on the integration test suite
