Electronics booking

This wraps up most all the electronic gear.  I'll be cross-referencing
(2 sources per recipe seems a good minimum) but most of it's locked
down.
Archery booking

Added two more recipe books and distributed the recipes to them & some
of the archery/survival ones.  Left the selfbow and field-point arrows
autolearned so folks aren't left completely unarmed in a no-city game.
Initial guidelines for melee weapon to hit bonuses.
Added a rechargeable battery pack mod for tools, rechargeing station for vehicles, added 'INTERNAL' vpart flag which requires the part to be installed on a tile with a 'CARGO' vpart and 'RECHARGE' which has a twin item flag, which allows the rechargeing vpart to charge a tool with the same flag..
Forgot item_groups.json
Remove commented code
Fixed gramar error.
Added DOUBLE_AMMO and RECHARGE charge display.
Fixed another grammar error.
Added flag info to JSON_FLAGS.md and fixed a few typos.
Fixed unloading issue. Also added non-unloadable notice as per KA101's suggestion.
Added another message about item not being unloadable.
Swaps a capital for a lowercase in armor.json.
Eases up on arrow and bow autolearns

Chiefly because selfbow & field-point ONLY might be a bit much for
no-city players.
Light survivor boots, gloves, hood.
Heavy survivor boots, gloves, helmet.
Because of derp.
Survivor boots, gloves, hood.
Winter survivor boots, gloves, hood, and mask.
Survivor firearmor boots, gloves, hood, mask.
