First iteration for 'Incognito mode'

For now this is just a private mode but with the following two twists:

- We use the dark theme.

- We steal our history and bookmarks from the main profile. This is
  done in 'read-only' mode though, so any changes made in this session
  will be lost.

Add command line options and a UI item to launch the browser in this
mode.
