initial implementation of batteries and chargers. they charge.
perform LoS checks on every pulse (#14)
batteries are just too cool for words now
Merge branch 'dev' into dev-energy
batteries retain charge when broken
batteries now charge from left to right
fixed some animations, did some refactoring, hopefully didn't break anything
Fixed itembox issues, return item on wire signal, show storage status on interaction
just can't get that damn animation fixed... gotta wait for the patch
Merge branch 'dev-energy' into dev
Merge branch 'dev-magnets' into dev
Added throwable magnets, but they don't work too well :(
Moved some files around
