Comment (by photocurio):

 @joemcgill I added your `wp_check_filetype_and_ext` to my functions files
 but it did not allow me to upload JSON.  I've also tried filtering
 mime_types, and no luck.  Yet, if I go in and add JSON to the mime_types
 listed in the wp_includes/functions.php, I can upload JSON.  Strange!
 Naturally I won't leave the wordpress core hacked.  I sure wish these
 filters worked.
