Remove color logging feature from qtestlib.

This feature was undocumented and only worked if a secret environment
variable was set, the test output was going to a real console, and plain
text test results were being generated.  Including code in testlib for
fancy presentation of test results conflicts with testlib's stated goal
of being a lightweight framework where every feature contributes to
finding bugs, so this feature is being removed.  If fancy presentation
of test output is required, it should be achieved by post-processing the
test output outside of the test framework.
