Final scripts

@will-moore @joshmoore @jburel : 
The scripts of Will & Josh & Colin are gathered here after testing and using for creation of a testing database for permissions testing. I have added Colin's script (CreatUsers.py) here to make a new de novo database creation even easier. Will added to Josh's original script the 
- ability to create datasets/projects on import (auto_import.py).
- Will created TagEverything.py which adds tags, ROIs and comments to all entities created/imported in auto_import.py script
- I have added new .inc and .users lists (...P.inc & ...P.users for plates import, ...O.inc & ...O.users for orphaned images import) - these are really laborious to do, I want to keep them in safe place
- possibly it would be nice to be able to produce new Screens via a script - it proved to be quite laborious to do it manually now (the tagging of Screens / Plates works within TagEverything.py script already though)

Would it be possible to have all this on Howe please ?
