e-newsletter widget improvents

Hi,

two simple additional options for the e-newsletter widget will improve its flexability.

1. Add two optional text/html fields
a) after the title / before the form, to enable call to action text that better explains why vistors should sign up
b) at the bottom after the form / submit, to add extra re-assuring text like 'we won't ever spam you' or see our privacy policy links

2. Allow optionally to use html5 place holder text instead of labels

Thanks for thinking about this.
