Added validation for rec create forms.

Fixes #98
Fixes #95

I tried doing it this way, but it doesn't actually work... did you test it? To do the validation it's checking the input w/ a `name` attribute of `first_name`, but that's not the case in the recommendation request form... the `name` value is `rec[0][first_name]`... I tried the above when I was doing the styling form for the field and realized the ValidationService provider would not work for this form. I might be wrong, but my attempt (which was the above) didn't work right.
