Improve /firefox/os/ animation performance. Bug 911674.

- Update intro bgs, phone screen, adaptive bgs, adaptive
  feature points, & adaptive sprites.

- Performance in A-grade browsers seems far better (based
  on Fx repaints and Chrome frames).

- IE 9 and below get a slightly degraded experience. Can
  be improved if necessary.

- Fix IE8 bug where birthday bg would never show up in
  top fading section.

If download is not possible, don't show scene2 on /new.

See bugs 891562 and 919788.

This also prevents scene2 from appearing if you manually update the location hash. Both of these scenarios could cause bogus download stats when the page is loaded in firefox-latest or fxos or an unsupported platform.

[fix bug 903091] Track telecom provider exits from the firefox os page
Improve use of scenes in /firefox/new.

See bug 919788.

This makes a few changes:

 * if you arrive on the page directly from #download-fx the animation is suppressed.
 * dowload is initiated in an iframe so current page CSS images don't get cancelled before loading.
 * scene2 is suppressed on Android
 * fixed bug in IE < 9 going directly to #download-fx
 * improve inline commenting
 * use LESS-CSS mixin for transitions in CSS.
