🔩 Add (plastanium) diode (#964)

* Add plastanium diode

* Only rotate the arrow part

* Use the sum of graph batteries from both sides

* Make diode send power overflow

Diode keeps one-way equalizing while the sending graph has batteries that are ¬ yet fully filled.

* Remove redundant block != null check

* Remove free power

* Stash

* Revert "Stash"

This reverts commit 0c14854519.

* Equalize graph storage percentage

* Update sprite

* Move nearby link check

* DRY

* Fire deathstar at extra spaces

* 〃

* Fix ghost rotation

* Please overlord anuke

* Mild cleanup

* Konami code

* 〃

* Lowercase float

* Newline begone

* Fix overclocking issue

* Fix rotation and name
