Feature request: Pass array to .unset()

[jrmyio]

It would be handy to be able to parse an array of keys to unset when calling unset().
this.model.unset(["prop1", "prop2"]);

Also, the docs on http://ampersandjs.com/docs#ampersand-state-set when using "unset" as option do not make clear what it actually does.

the unset parameter probably isn't worth documenting. It's in there because it was inherited from the backbone source (that's how it does .unset()). unset takes all the same parameters and should be how people unset things imo

[wraithgar]

set('foo', {unset: true}) would also bypass the defaults.

This was discussed some in the irc channel this week and some people are wondering if we even want .unset(). What is your use case for that?

[jrmyio]

I wanted to set half the model to its default settings without me actually writing these default values as these are already part of the model description. Is there a different way with "set" to do this?

[wraithgar]

Ah ok yes the required/default thing seems to be confusing people. If you set required:true and also set a default then that default will be set on model instantiation.

Would also like to see unset take an array. I have an app that needs to unset quite a few attributes at once and each change event fired does some kind-of expensive stuff that I'd like to avoid running 20 times.

Willing to submit a PR if nobody else is biting.
