Add support for latest angular-material version

[elyas-bhy]

The latest version of angular-material (1.0.4 at the time of writing) is currently not supported in angular-form-for.
Namely, forms cannot be submitted using the latest version.

Can you provide a Plunkr demonstrating this?

Using angular-material@1.0.4, clicking on the submit button does not do anything.
However, if you use an older version (change the js/css to 0.10.0 for instance), then the submit works just fine.

Ah, so a major release has gone out since I last integrated. Makes sense that something would break.

I'll see if I can take a look at this sometime. Happy to accept a PR from you if you get to it before I do. :)
