1.1.1 - Refactoring

• Remove hard requirement of ext-xhprof from composer.json, because package can work with ext-xhprof and ext-tideways_xhprof depending on PHP version.
• Added suggest block with hints about proper extensions.
• XHProf will be configured on bootstrap stage before automatic run. This will allow to have configured XHProf instance from component if profiler will be executed manually in another place.
• XHProfComponent::stopProfiling() now returns links to reports instead of void.
• Added param tmpPath in component to define temporary directory for profiling results.
