Adds CONVERT Gates, for converting a signaler signal to logic or vice-versa. Restructured/renamed some of the new logic files - Split up the logic_gates.dm file into three files - mono_input.dm - dual_input.dm - converter.dm Made the logic_gate machines auto-update their multitool menu when you click the links Made the logic gate circuit boards a product of the autolathe - Take that science. Quit hogging all the boards, nerds. Removed relative pathing from signaler.dm

|
A quick note regarding NOT Gates:
|
|
- Connecting multiple things to the input of a NOT Gate can cause weird behaviour due to updating both when it receives a signal and when it calls process().
|
|
- This means it will attempt to output once for every logic machine connected to its input's own process() call.
|
|
- It will then attempt to output an additional time based on the current state when it comes to its own process() call.
|
|
- For this reason, it is HIGHLY RECOMMENDED that you only connect a single signal source to the input of a NOT Gate to avoid signal spasms.
|
|
- Connecting multiple things to the output of a NOT Gate should not cause this unusual behavior.
