Prevented array to string conversion in the junit formatter
Made the Behat suite compatible with Windows and ConEmu/AnsiCon

On Windows, the support of colors is detected based on environment
variables set by ConEmu or AnsiCon rather than the input stream like on
Unix systems. So the testsuite could run the command with a decorated
output which would then fail to match the run stats.
Refactored a spec to make it pass on HHVM

HHVM implements __set and __get in ArrayObject while Zend does not, so the
spec using ArrayObject to test not found properties was failing.
Marked HHVM as officially supported
