Add TextArea field type for Custom field of a magic link template

[ahillbilly]

Currently in the Magic Link template creation page, you can add D.T fields to the form as well as a custom labeled Text Field. This text field is a single line text field which is handy. I'd also like to include a TextArea field so that the user can feel like there is more space to write a longer comment.

Ok... I was just shown how to change this after adding it. I think I'd generally want to set it upon creation in lieu of being able to edit it later as field type in most places isn't editable after creating it. The webform plugin a good parallel example.
