Retropie Portable Gaming Device (remixed Pocket PiGRRL)

That Pocket Pi Grrl has some changes from original. It includes :
- a Raspberry Pi Zero
- custom controller with a d-pad, a/b/x/y buttons + reset & start
- PiTFT 2.4" 320x240 display
- 2000 mh Lithin Ion battery + charging circuit
- no speaker but a jack connector

pgp-top.stl and pgp-bottom.stl are from [original Pocket Pi Grrl](http://www.thingiverse.com/thing:807591)
I’ve made some changes in top.scad and bottom.scad to fit my changes.
