* Mimes
*
* This file contains an array of mime types. It is used by the Upload class to help identify allowed file types.
*
* When more than one variation for an extension exist (like jpg, jpeg, etc) the most common one should be first in the
* array to aid the guess* methods. The same applies when more than one mime-type exists for a single extension.
*
* When working with mime types, please make sure you have the ´fileinfo´ extension enabled to reliably detect the
