Paypal and Coupons

[JustinSGray]

Create a transaction object to be included with
* Clubs (pay for access to the site)
* Registrations (pay for event registrations)
* Memberships (pay for membership to club)
* Possibly use subscriptions?

Create coupon objects to be able to issue discounts
* Can be tied to specific users (but does not have to be)
* Can be limited to one use per user
* Can be specified as dollar amount or percentage
* Can be set to expire
* Can be set to be used a certain number of times
