Watch multiCheckbox model value to support async options

[m0t0r]

Hi, @kentcdodds. I've added changes to watch model value so that support async options values (related to #32 ). Please, take a look. I didn't find a better approach. For performance improvement I use for loop over angular.forEach which is not the most performant solution.
As a last thing I added documentation for the multiCheckbox form field. I'll add an example for this field once the PR gets merged.

Thank you

Sounds good. I don't think there's really a concern for performance where you swapped the for loop for the angular.forEach loop, but meh. Just making sure, this covers your use case right? You tested this with your stuff and it works?

[m0t0r]

Yes, I've created a demo example locally and it works as expected

[m0t0r]

Unit tests are not established here, so I didn't create test cases

[kentcdodds]

Yeah, this library still needs some love for sure. I'll merge this and create a release. Perfect PR. Thanks.

[m0t0r]

Cool, thank you 👍

Done: npm install [email protected]

@kentcdodds can you publish changes to bower, please ? I cannot get 4.4.0 on bower

[kentcdodds]

Whoops! I forgot that my npm run release is different in this repo and I forgot a step. It should be available now!

[m0t0r]

@kentcdodds I am afraid it will not work, there was no new release created. I still get previous version.

[kentcdodds]

Ah! :-( I didn't notice my console totally borked on me. Try again, I just pushed it :-( Sorry @m0t0r!

[m0t0r]

No problem. It works now, thanks for support 👍
