This is a significant revision of the PHPUnit documentation. This specifically:

* Adds concrete examples of writing tests in various styles (`CiviUnitTestCase`, `CiviEndToEndTestCase`, `civix`)
* Adds reference documentation for classes/traits/interfaces provided by Civi's test library
* Imports key information from Testapalooza docs (#389)

Changed `civix generate:custom-data` to `civix generate:custom-xml` as the former is incorrect. Also corrected grammar in subheading "Extending a subtype".

There are usually a few branches to choose from when picking a base-branch.
This breaks out a table to differentiate them.

Include Survey in the list of pre and post entities and alpha sort the post entities like the pre entities

* CRM-20981 - Call `useApp()` instead of stringing together fiddlybits.

MkDocs was displaying this without the space between div and ng-app.

* Custom ng base pages - re-arrange content

* loader.md - Put the load() call in the right spot
