Deprecating UIActionButton (Part 1)

Summary: Replaces calls to UIActionButton with <ui:button>.  I tested most
         of these calls, but there were some that I didn't know how to
         reach, so if you are one of the owners of this code, please test
         your feature in my sandbox: www.ngao.devrs013.facebook.com

         @brosenthal, I removed some logic that was setting a disabled state
         on a UIActionButton, which is actually a no-op.

Test Plan: www.ngao.devrs013.facebook.com

           Explicitly tested:
           * ads creation flow (add keyword)
           * ads manager (conversion tracking)
           * help center (create a discussion)
           * new user wizard (next step button)
