Handful of feature requests

[internetdj]

I'm glad I found this module. It provides much needed do-it-yourself marketing for our members and automation that makes my life easier as the site owner.

This could be even better with some of these features (in order of priority):

1: CAPTCHA on the sign-up form
2: Allow admin to select a day duration for fixed quantity ad packages (how many day to run), so campaign has an expiration date and the banner impressions spread evenly across a fixed number of days.
3: Authorize.net integration

Thanks,

Michael
