Add filter to ajax discount code

This allows for plugins to create discount "aliases", thus preventing the need to create tons of different discount posts.

Example use case:

A user enters their existing license key. A plugin could validate the license key and, if successful, replace it with the (existing) "RENEW" discount code.
