Title: Use filterable HTML5 'placeholder' attribute for checkout fields...

... and deprecate use of inlineFieldLabel JavaScript.

First attempt at issue #313

Currently recreate old functionality where fields were pre-populated with field labels.
Personally I think these should be blank by default but filterable so people can add.
