fix($compile): always instantiate controllers in parent->child order

Previously it was possible to get into a situation where child controller
was being instantiated before parent which resulted in an error.

Closes #2738
chore(dump): remove dead code

This code is not being used any more and the test is now failing
due to Karma changes. Karma used to expose window.dump but that
changed recently and that's why our build is now failing.

I'm removing the code and test, but we still need to figure out
how to route window.dump through angular.mock.dump, but that will
have to be a separate commit.
fix(dump): Prevented window.dump from being overridden by karma-jasmine.

In commit 6820322db562382fac903be35831275948825317 of Karma-Jasmine, the
dependency on angular.dump was removed. This caused two undesirable side
effects in the angular.js project. 1) Tests for presence of mock dump were failing,
and 2) the default window.dump was not outputting valuable angular-aware info. This
simple fix adds window.dump in testabilityPatch, to preprocess dumped input prior
to passing it to the global dump method.
docs(index): add seed app link to menu item
docs(cacheFactory): correct typos
docs(bootstrap): Note that ngScenario requires ngApp

ngScenario expects an ngApp directive to be used, and doesn't work for
manually bootstrapped apps. The failure mode is to hang on navigation.

Trying to make this wont-fix bug less obscure by documenting it.
Eventually Protractor will replace ngScenario and fix this.
