Fixed the prize mailer for sgdq, fixed some bugs in viewutil
Merge branch 'master' of github.com:uraniumanchor/sda-donation-tracker-2 into testing
Complete re-structure of bids
- Bids can now be hierarchial, meaning you can can sub-choices beneath a root choice
- There is no longer any choice/challenge distinction, choices can have goals, and challenges can have options
- The UI parts of this will probably need some work, but at least from a functionality standpoint, it works.
Added the ability for donors to select their own alias, visibility, and contact e-mails.  Thouroughly untested however.
