Aura Shell needs to exist on Mac

Adds first cut at "Aura Shell.app" on Mac.  The 'ash_shell' is extended
to generate a Cocoa application.  This application brings up a single
window containing the Aura desktop.  The main view of this window provides
an accelerated surface to Aura in which it can composite and draw its
results.

What works:
  - The application launches and renders the Aura desktop and background
  - Mouse movement, clicking, double-clicking, and interactions with
    Aura windows and widgets
  - Text buttons render with Skia text (needs improvement)
  - Non-modal transient window button
  - Window-modal window button
  - System-modal window button
  - Example Widgets button (checkboxes, radios, buttons)
  - Lock Screen button
  - Create Non-Resizable window button
  - Create Pointy Bubble button
  - Create Widow button
  - Switcher and Taskbar

What doesn't work:
  - Open Views Examples Window button
  - Views menus
  - Views scrollbars
  - Views accelerators
  - Views tooltips
  - Drag and drop
  - Anything involving MessageLoop dispatcher logic
  - Mouse movement doesn't pass through to Aura when mouse button is up

Note: Required .gyp flags are:
  'use_aura': 1,
  'use_webkit_compositor': 1,
