Update emails with text they want.
Fix some typo issues (dunno when they happened.. probably when converting html to slim or something) that prevented admin emails from being sent out.
Add '::' in front of UserMailer calls.
Only email superadmins, not all admins, if grants fail or succeed.
Note that a successful crowdfund had to have been 'funded' by a superadmin.
