Title: New error function to quickly extend new JS errors

This utility method has been quite handy for me when defining custom errors. Hopefully the underscore community agrees.

Sorry about jumping the gun on writing the docs. I didn't notice the contribution guideline until now.

Thanks @jashkenas for all your hard work on underscore and backbone.
