Pinebook missing screw from the factory

[Arwen]

Screws, estimated dimensions, (until we can get confirmation)

   M2 flat head machine screws
   8 x 6mm in length
   2 x 4mm in length

they should be 6 x 6mm and
4 x 4 mm

Done, thank you.

And, I added a note that the 4 shorter screws are used along the front edge. Might help someone putting it back together.
