More HTML Validation and User Notification suggestions

HTML Validation:
You guys did a great job on fixing like 99% of the HTML validation, but one thing remains a problem for us anal retentive folks. When you have a field that isn't required the HTML is still outputting

<span class='gfield_required'></span>

which it's invalid to have an empty element. This should be an easy fix line 612 of form_display.php and just have $field_content either display the span or not display the span based on if $field['isRequired'].

My next suggest is about the User Notification. There are some instances where the "Notification to User" might need to support the ability to populate it w/ an "email field" is there a way that can be added? Or is there a reason that the option was not implemented in the that specific portion of the notifications.

Thanks,
Lucas

Yea sure thing ... here's an image of what I was trying to express:

The "Notification to Administrator" allows you to select an email from a pre-populated "email" field, but the "Notification to User" does not. A case where this is needed is would be if you're using GForms to do a "Tell a Friend" feature, where the email should go to the friend but show that it's coming from you. Just from a usability standpoint someone is more likely to open an email coming from friend@mypersonaladdress.com instead of a generic email like noreply@foo.com
