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.
docs(overview): improve grammar
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);
  });
chore(ngdocs): fix the version jumper

correct the ordering and make gen-docs prepare the list of versions
during the build process
test: rename / remove duplicate unit tests
test(docs): ignore some of the specs on IE

This target was never un on our Jenkins CI. Some of the specs are using animation stuff, that IE does not support, so I'm disabling them.
chore: run more browsers on Travis (IE8,IE9,IE10,Safari,FF)

Also instead of running everything in parallel, there are only two parallel tasks:
- e2e tests running in the background (only on Chrome)
- all the unit tests running sequentially
chore: use only polling on Travis/SL
chore(travis): clean up logs

Forward SauceConnect logs and Karma debug logs into a file and print these files at the very end of a build.
