added: Phaser.Utils.getProperty / Phaser.Utils.setProperty; added: Phaser.Group.checkAll

Added deep-property getting and setting via strings:

Phaser.Util.getProperty(someObj, 'foo.bar.baz');

Phaser.Util.setProperty(someObj, 'foo.bar.baz', 'lol');

Added a "checkAll" method to Phaser.Group that returns true/false if all of the children's given properties match the value passed in.

this.someGroup.checkAll('foo.bar.baz', 'lol'); // will return true if child[n].foo.bar.baz === 'lol'

Comes with standard 'force' ability.
