Adding in support for multiple routes definitions through an array

[HelloChrisBrown]

Feature discussed in issue #89

Thanks @nickl- for supplying the code

This addition would allow you to define multiple paths to the same routine. This would be useful in cases when you want to pluralize.

$r3->any(array('/User', '/Users'), function(){
     return 'Hello World';
});

@blindsamson is it working? Awesome! Tx for the pull request!

Would you do us a huge favour please? We need a unit test for this and updating the documentation always helps. =)

Tx a million, glad I could help.

@nickl- I haven't forgotten about this. I have been slammed at work. I'll get to it asap.
