Added 2 more reward categories [REST How-to Pack & REST Master Pack]

Based on feedback from those who already owned the CLSA book, there are 2 new categories added:

• REST How-to Pack
• REST Master Pack

This is to allow those who already owned the CLSA book to get the latest book (on REST) at a huge discount.
