cesky-hosting.cz úprava třídy Debug

Protože jsem byl „nucen“ využít hosting cesky-hosting.cz, narazil jsem na problém s ini_set resp. ini_get – upravil jsem proto metodu Debug::enable – doplněn parametr, který zabrání kontrole nastavení logování chyb, které na tomto (a asi i jiném hostingu) spadne do chyby – bílá obrazovka.

asi to není nejčistší, ale pokud je odladěný projekt na lokálu, lze ho přenés a spolehnout se na mailové zapisování chyb …
