fix(dialog, menu, select, interimElement): use $animateCss instead of transitionEnd events.

replace programmatic use of element.css for style changes and use of transitionEnd event listeners with use of ngAnimate's $animateCss; use polyfill for Angular <1.4.

$mdUtil.dom.animator.translate3d() uses $animateCss() instead of waitTransitionEnd()
use animateCss.js polyfill for 'material.animate' module
- add mock `createMockStyleSheet` for animateCss tests
refactors to menu-interim-element.js and select.js
- refactor logic and patterns used
- use $animateCss in place of waitTransitionEnd()
debounce Select and Menu window resize handlers
Dialog uses same showBackdrop/hideBackdrop pattern as Menu and Select
select async demo no longer clears users list when reloading
select demos use `md-input-container { margin-right: 10px;}`
hide Select Backdrop with zero duration
enable full click detection in select-value area by using background color (with zero alpa).

BREAKING-CHANGES:  select and backdrop styles added

*  select list text is not selectable,
*  select backdrop hide duration is 0ms
*  select text value background has zero alpha

```scss
.md-text {  @include not-selectable(); }

.md-select-value {
  background-color: rgba(0,0,0,0);
}

md-backdrop {
  &.md-select-backdrop {
      transition-duration: 0ms;
  }
}
```

Fixes #3919. Fixes #3837. Fixes #3773, Fixes #3640. Fixes #3527. Fixes #3653.
