Title: Add existence test for methods being bound in bindAll

When bindAll encounters a method that doesn't exist on the object methods are being bound to, it throws an error with the format: Method doesn't exist: methodThatDoesExist.

This is more useful than the standard "Object doesn't have method bind" error. Certainly when you have a Backbone view with dozens of methods.
