Give option to not include source on tax receipt
I don't know if it is just us that does this, but we don't want to include the source field on the tax receipt as we have details in there that we don't want donors to see (mostly tracking where the donor click came from, but also sometimes people just type in something that's not donor friendly when entering offline donations). If it's just us, I can use the Drupal module to adjust as needed, but if this seems like something that would be more broadly useful to others, I could submit a PR to add a setting.
