Change screenshot filename to have date time

Browse source 
Format fgfs-YYYYMMDDHHMMSS[-#] where the # is for the rare case when there are multiple screenshots per second.

The change makes the filenames sortable based on date and slightly improves run time performance when there are a lot of screenshots in a particular directory
