Uploaded file sorting

[pholterm]

I am uploading NMEA data with filenames like this:
2014.06.05_13.01__2014.06.05_13.09___DATA0001.DAT
with the first and last GPZDA record as the dates in front of the original filename.
This helps me to keep track what I have uploaded. When I now upload a bunch of these files, they are not necessarily sorted correctly. It would be nice to be able to sort the filename list according to their filename/upload time/upload index.
