Route method Annotation modifications.

This push is in reference to [Issue #122](https://github.com/peej/tonic/issues/122). I have verified this change with my application, I can now use __@routeMethod__ as apposed to the @method annotation which conflicts with phpDocumentor.

> Added configuration option `methodAnnotations` and associated private property in __Application__ class.
> Option defaults to _'method'_ & _'routeMethod'_.
> Inserted `methodAnnotations` check loop in method `readMethodAnnotations`.

Please verify with your testing suite that I have not introduced any errors or issues; I'll be happy to help correct further.

Thank you,
Sam
