Add option to remove "Website" form field

[flux77]

In the default Isso comment form, there are four form fields: content, name, email, and website. If I have no use for the "Website" form field, how do I remove it? Of course, I could remove it by using some CSS rules, but is there a better solution?

Perhaps there could be a data-isso-website-field option that controls whether or not to render the "Website" field.

This could probably be done with CSS, but in the interest of accessibility, we should have a server-side options matrix:

Field	Status
Name (Author)	Disabled / Optional / Required
Email	Disabled / Optional / Required
Website	Disabled / Optional / Required
