Added another test case from #571.
Updated the output of TapParser::processTestLine.
Broke TapParser::parse down in simpler methods.
TapParser: ignore leading garbage and properly complain on missing TAP log.
TapParser: detect and report duplicated TAP log.
TapParser: got rid of the "test" and "suite" values.
They are only available with PHPUnit.
TapParser: append the message from yaml diagnostic to existing message.
Reworked the dispaly of test results.
PHPUnit plugin: pretty print test data.
All the DB/host fields have a space after the colon, which is much better as it means the text you type is slightly separated from the prompt. However, the admin user fields didn't include this space which was inconsistent and made the install script a little less professional.
I have therefore added the missing space for the prompts which didn't have it in the English language file, and have also updated all other language files to also use this format. Most of them followed the same inconsistency as the English version, though some were consistent but without a space, and some which were differently inconsistent (both internally, and between languages).
