cult IPCs refactor (#4734)

Thread for discussion

This:

Makes IPC being convertable to cult

Does not allow IPC to draw runes, as they have no blood

Makes all cultists immune to cult's EMP. This way cultist IPCs and organics with prosthetic won't be killed in friendly fire.

Removes heat generation from EMP rune
