Config to set schematics folder

[TomLewis]

Can we please get a config option to set the schematics folder, this allows us to use schematics cross server without using a symbolic link, but also, if we are able to set the folder to be inside the FAWE schematics folder, we can list schematics in-game, and also //paste them to quickly get a copy of a previously made ship.

This might work, but I'm afraid of all the various errors that may occur. I'm not against implementing this, but it's not going to be a high priority.
