ui-sortable options for array decorator

[crcornwell]

This (tiny) change allows ui-sortable options to be passed into the directive via an optional sortOptions key on the form.

e.g. adding

"sortOptions": "{'cancel': 'ol'}" 

will disable sorting. This is particularly useful if you want certain arrays to be sortable but not all of them. It also opens up the ability to make use of all of the possible options listed here.

Hi @devSoss, nice little PR! Thank you.

Sure thing @davidlgj, happy to help! I also went ahead and updated the docs in the main repo so you can check that out when you get a chance.

Hi again @devSoss, just a heads up. We've having some trouble with the options passed along as strings. In certain cases it seems like it throws an exception when no option is passed.

So I changed ui-sortable="{{form.sortOptions}}" to ui-sortable="form.sortOptions", which means you have to pass your config as an object, not as an string:

"sortOptions": {"cancel": "ol"'}

It's in develop right now but will come out next release.

Ah okay, good catch @davidlgj, that slipped by me.
