Zach Copley 962eed904c - Use a stripped down new notice form for FB app because FB canvas apps
can't support image upload via multipart/form-data (and location sharing
  is iffy).
- Deal with new error code 100 from Facebook, which seem to be for
  inactive accounts.

* location (from FB) and they don't allow posting multipart form data
