Class Name:
- WindowManager.h
Abstract:
- The Window Manager takes care of coordinating the monarch and peasant for this
  process.
- It's responsible for registering as a potential future monarch. It's also
  responsible for creating the Peasant for this process when it's determined
  this process should become a window process.
- If we aren't the monarch, it's responsible for watching the current monarch
  process, and finding the new one if the current monarch dies.
- When the monarch needs to ask the TerminalApp about how to parse a
  commandline, it'll ask by raising an event that we'll bubble up to the
  AppHost.
