Closes #4675
chore(end2end): remove old references to the scenario runner and update to point to protractor
chore(testing): run end to end tests on firefox and safari as well as chrome

Update the Travis and Jenkins configs to run protractor tests on Safari and Firefox as well,
and make the Travis tests run output XML and turn off color.

Fix tests which were failing in Firefox due to clear() not working as expected.

Fix tests which were failing in Safari due to SafariDriver not understanding the minus key,
and disable tests which SafariDriver has no support for.
refactor(testing): run end to end tests on separate browsers in parallel
chore(testing): fix Jenkins breakage due to test directory already being present
docs(angular.forEach): add missing space in test

Closes #6130
fix(mocks): remove usage of $animate.flushNext in favour of queing

The flushNext method of testing is difficult and highly coupled with the behavior
of ngAnimate's $animate workflow. It is much better instead to just queue all
$animate animation calls into a queue collection which is available on the $animate
service when mock.animate is included as a module within test code.
fix(mocks): rename mock.animate to ngAnimateMock and ensure it contains all test helper code for ngAnimate

chore(travis): remove double bower install to test if it's still needed

We did this due to travis-ci/travis-ci#1293 but since it's possible that this hack is not needed, I'm removing it.

If it turns out that we do need it still then we should ping the travis issue and revert this commit
