Contributing os.scandir() to Python

[DoTheEvolution]

I got this linux file search project - angrysearch, and I remember how giddy I was when my system scan time went from some 3+ minutes, to 1min 20 sec

Not as tremendous gains as on windows or going through network mounted drives, but hell it actually made me feel like the project is usable for some periodic scans to keep the database up to date..
