auto_import.py adapted for mixed FS-non-FS testing 

@joshmoore, @jburel: This is adaptation of Josh's script for automatic import to Gretzky (originally).  
This is the first of series of adaptations of this script. The intended usage is for the double upload to create the mixed FS & non FS database (import to Howe, upgrade Howe, import to  Howe again, now as FS, create mixed database...).

I have tested it on dev_4_4 build from today on local machine and it works. I have put in more users and images to import (added fixed formats like MIAS and some formats from the  "must have" list from the first internal demo.

Other "sister" scripts for uploads for other purposes will follow (as well as upgrades of this one).
