chore(travis): reorganize protractor configs to group by spec instead of by browser

Use the multiConfiguration ability of Protractor to start tests on multiple browsers
from the same travis cell. Group tests by type (jquery, jqlite, or docs tests) instead
of by browser. Turn on tests for jQuery.
perf($cacheFactory): skip LRU bookkeeping for caches with unbound capacity

chore(doc-app): ensure only canonical paths get sent to Google Analytics

Before we were simply sending the current location, but multiple URLs map
to the same document.
Now, we use the canonical path of the current document if available and
fall back to the $location path otherwise.
Includes tests!!

Closes #6402
chore(docs-app): re-activate docs-app test tasks

be run as part of the test tasks.

docs($animate): change @param to use valid types

`{jQuery/jqLite element}` is not a valid jsdoc type and breaks when being
parsed causing the documentation to look wrong.  This commit changes all
such param tags to use `DOMElement` instead, which is what is used for
similar params in `$compile` and `angular.element`.
