Updates for new power and connector PCBs, and other fixes

- Fastex clip broke - reinforce
- Epilog still has artifact where Battery strap arrows are cut instead
of just etched
- Add more space to get battery strap on?
- Adjust battery strap width? (0.3"?)
- Move RasPi box etching ~1/64" to the right
- Shorten length of tab that hooks lid into place, so that lid comes
off easily and wont break tab.
- Redo USB Power adapter for new PCB
- Add cutouts on lid for vertical mount of lid so it doesn't slip
left/right.
- Increase holiness of speaker holes.  Perhaps do a large single hole
with a plus sign in it.
