Title: Adding validateAll feature to Backbone.Model during set or save

This commit creates a new `validateAll` option that can be passed when saving or setting one or multiple model properties. A sample use case for this option is **form validation**.

Often during form validation, a developer will not want all model properties to be validated at the same time. Instead, a developer might want to validate individual properties one at a time (even after these properties have already been "set"). Thanks!
