2.0.1 regression

errorHandler 'onShutdown' handler inadvertently registered after the output 'onShutdown' handler... (fatal errors being logged after output occurs)  :(
Fix:
 * errorHandler now subscribing to 'php.shutdown' via eventManage (with higher than default priority for good measure) - was using register_shutdown_function()
 * added unit test to assert that errorHandler::onShutdown subscriber is before internal::onShutdown
