* method: getFileExtension
*
* Obtain the file extension from a given filename and if found, store the mime type in the cache array

* parameters:
* $filename - The filename to obtain the extension from
*
* returns:
* Boolean false if the extension was not found, or the extension if it was found
*
* notes:
* It's inconsistent to set the cache param for the mime type here, but not the file extension
* As where this function is used, it's almost always used when setting the file extension, perhaps
* This function should be called setFileExtension instead and just return the extension afterwards
* Then we could hide the set cache param for the file extension inside here too and clean up the code
