Remove usage of deprecated DebugClassLoader, ErrorHandler and ExceptionHandler

Not sure if you want to maintain support for now to symfony 2.2, but as composer by default also upgrades to 2.3 I forked and upgraded for myself.

I upgraded symfony in composer.json to 2.3, added symfony/debug and use the new Debug::enable() function.

Maybe you would like to merge this.
