Don't crash when not compatible mod is detected

A good idea would be to disable the uncompatible mods instead of crash, I don't remember the exact way it is right now.

I think #323 is a better approach

This way you could run it with every mod, but they would be disabled, after startup you can have info about the disabled mods.

I understand it would be easier to use (no need to delete/move mods) and it would be provide incompatible mods, but incompatibility needs to be testing and even though Minecraft is the most popular game ever it still lacks testers. That's my opinion, not a dev.
