Changed unique traces to exclude suppressed traces so they don't have to be filtered later.

Changed ClassicTheme to emit line break before trace colour block instead of inside.
Renamed CapabilitiesTest::testGigaSlow -> testVerySlow.
Updated Readme.

 * Display the name of each test case as it is executed.
-* Display the execution time of each test in tiered colour bands.
+* Display the execution time of each test in configurable, tiered colour bands.
 * Immediately print exceptions, assertion failures, warnings, notice and deprecation messages as they occur.
 * Flawless test suite indicator: success dot turns to red exclamation mark if any prior tests failed. Useful for CI consoles without a scrollback buffer.

 ## Testing Pip
 
-The printer's capabilities are exploited via `CapabilitiesTest`. However, this test file isn't run directly because many of these tests are designed to fail. Instead, we write tests that run PHPUnit internally, each of which invokes one of the capability test cases and verifies its output.
+To run the full test suite, use the following command.
 
-The real tests, also known as *functional tests*, are located in `test/functional`, written in PHPT format. PHPT is a [scarcely documented format](http://qa.php.net/phpt_details.php) designed to support [testing PHP itself](https://qa.php.net/write-test.php). An undocumented feature of PHPUnit is its limited support for a subset of the PHPT test specification, which we exploit to test PHPUnit itself with our printer implementation loaded.

-### Writing a functional test
+### Writing functional tests
 
 To test the output of a particular capability we run `CapabilitiesTest` with the `--filter` option to target a specific test case. Each functional test contains the arguments passed to PHPUnit in the `--ARGS--` section of the file. These arguments can be pasted directly after the PHPUnit command to see the resulting output from that test case. We verify the output in the `--EXPECTF--` section of the file.
