desktop.Status && desktop.StatusGrid: implementation

* app_back:
  include PID in control channel default message

* app_front:
  gather first status message about backend loading both native and http UIs

* view.desktop:
  - sizeIn and sizeout effects for Status in Desktop init
  - minor style changes (Desktop && Status)
  - StatusGrid with proper size, configured columns and store (with models)

* l10n:
  needed additions

  MVC-like directory structure is OK. In Editor same file names in tabs
  differ in hover tooltips. But for informative navigation on FS it's OK.

+ models:
  + Base.js
  + Status.js

+ store:
  + Status.js
