[WIP] Modular effector

I have made an evolutive effector based on an E3Dv6 but i wish add more compatible hotend later an maybe more...


In my specification i have:
 - Compatible with other types of HotEnd
 - Can add support for feature tools
 - Can have two fan blower
 - can add a top-module for a direct-drive (or something like that…)

Need threaded insert of course ! :D
