bring back an upload method to FileMaker Server

Idea created by Markus Schneider on Oct 26, 2015

    often, we have access to FMS on a clients site - but there isn't always a FM client installed (or, we have a client but there is no way to load a file because of locked USB ports), etc.

    therefore, it would be great to have the upload method in FMS - as it was before FM13
