Changes App init so config is set with setConfig(Config $config_object). This needs to be set because the reliance on the default config was removed. A Latte instance is now optionally created with enableLatte, this will throw an exception if the config has not yet been set. This allows the default config assumptions to be removed and Latte to be enabled only if you are using it within your app. If you were building an API previously a Latte object was created, now it would not be.
