CustomTextField & sign up form should support fields without icons

[ened]

As written in the subject, we would like to remove the images from our custom fields:

$0.customSignupFields = [
    CustomTextField(name: "given_name", placeholder: "First Name", icon: LazyImage(name: "974-users"), validation: handleGivenName),
    CustomTextField(name: "family_nane", placeholder: "Last Name", icon: LazyImage(name: "974-users"), validation: handleFamilyName)
]

=> The icon field should become optional.

Hi @ened

I feel this would not be in keeping with the primary fields such as email and password, you could use a transparent image although again this gives you an inconsistent look and feel

@cocojoe Get your reasoning, yet still two comments:

1. Auth0's web-version allows me to remove the icons. It looks just fine.
2. Any icon recommendation for first & last name? :-)

1. That's a valid point, let me discuss internally.
2. Personally I would go generic with a head type icon perhaps.

@ened we can add this to our backlog
