docs(guide): warn about module creation versus retrieval

Updated Module documentation to include the suggestion of the top-rated comment: "This documentation should warn that "angular.module('myModule', [])" always creates a new module, but "angular.module('myModule')" always retrieves an existing reference."
docs(changelog): release notes for 1.0.8 bubble-burst
docs(module): improve the installation instructions for optional modules

Currently, the documentation does a bad job of explaining the distinction between the services that it provides,
and the module itself. Furthermore, the instructions for using optional modules are inconsistent or missing.
This commit addresses the problem by ading a new `{@installModule foo}` annotation to the docs generator that
inlines the appropriate instructions based on the name of the module.

revert: fix($sce): allow IE7 standards mode to pass non-quirks mode test

This reverts commit 637c9b1611c5a75a42048ee1c591521c7031751a.
(ref #3633 and #3646)

The minimum bar for $sce is IE8 in standards mode.  IE7 standards mode
is not supported.  If you must support IE7, you should disable $sce
completely.

  angular.module('ie7support', []).config(function($sceProvider) {
    // Completely disable SCE to support IE7.
    $sceProvider.enabled(false);
  });
feat(ngMock): add support for creating dynamic style sheets within test code
fix($animate): only execute a timeout when transitions or keyframe animations are used

ngAnimate causes a 1ms flicker on the screen when no CSS animations are present on the element.
The solution is to change $animate to only use $timeouts when a duration is found on the element
before the transition/keyframe animation takes over.
fix($animate): skip ngAnimate animations if the provided element already has transitions/durations attached to it
