v0.5 (second batch with minor fixes)

Fixes found and made:

• use switch with thinner base to fit under to top plate for function keys
• push USB-C out from main board to stick out to the edge of the case
• fix spacing of fn keys (they were really whack in v0.4)
• add grounding plates for mounting holes to prevent a bit of EMI from metal screws
