Reorganize "Testing" pages

Updated link to info.xml reference

Page should not link to itself.

Documentation for hook_civicrm_alterEntityRefParams

I'd like to be able to merge the general, incremental improvements for the
"Testing" section, but these two new pages aren't yet written.  Comment them
out.

 * Provide a better visualization of the the different test suites
 * Migrate setup instructions from https://github.com/civicrm/civicrm-core/blob/master/tests/README.md

1. Add new entries for Protractor, Codeception, and QUnit

2.  This menu includes (a) some pages about the overall testing process and
(b) some pages about specific tools.  Consistently put the general before
the specific.

There are multiple tools for testing in JS. We'll want separate pages for each.

The second statement doesn't make much sense without the first statement.
Put them together.

Running civilint is important for any/all code.  Seems a bit arbitrary
emphasizing this point specifically for tests.
