Automatically assign sub-labels to complex inputs

[stevegrunwell]

The autocomplete attribute specification supports more detailed values (e.g. "honorific-name", "given-name", "additional-name", etc.), which would make sense for complex fields like "Name".

Instead of just saying "the first input represents a name", we'd be able to say "when building a complex name field that has the autocomplete attribute of 'name', the first name has an autocomplete value of 'given-name', the last name is the 'family-name', etc."

To avoid false positives, the user would still have to assign "name" as the autocomplete attribute on the Gravity Forms field, but the inputs could then receive more appropriate values.
