Adding new Launcher behavior

This is only an intermediate CL - trying to keep the CL's in a handle-able size.

The new features of the Launcher behavior are:
  - Group running programs (V1, V2, Browsers) under existing launcher application icons. 
  - When a V2 app gets started and it is not pinned to the launcher, it will be added for it's lifetime to the launcher (and disappear after the last incarnation goes away).
  - Each shown launcher entry can ...
     + .. show a context menu (right click) which can e.g. close all applications of that type.
     + .. activate or create such a type upon first click.
     + .. produce a list of running "apps" upon click when one of the applications has already a focus. [more to come]
     + .. [maybe] produce a fancy hover menu. (at the moment it produces the bubble help)
  - The list of apps (as described above) contains ...
     + .. The name of the app itself.
     + .. For each running instance the favicon & the title & (not yet implemented:) an icon for incognito.
  - The new features are behind a flag.

The full specification can be seen here:
 https://docs.google.com/a/google.com/document/d/1i39rO8uERWwTvV0e0TDtelgGjzU9Wj5L6CldMl9y6lE/edit


This is the second CL for these new features, however there are still several things missing which will be addressed in more CL's:

  - More unit tests (activation state tracking, V2 apps)
  - The "eye candy menus" (mocks are still missing) ..
    + .. including incognito marker
    + .. a definition how the menus get sorted
    + .. the open question about click or hover menus
    + .. touch integration
  - The browser icon should be movable as well
  - Rip out old classes and unused complexity - which can only be done after the flag gets removed: At the moment, the changes are trying to stay within the existing architecture to make it possible to switch with a flag.
