Fix: Mimic CC:T config file structure

Replaces the jankson implementation with night-config. Night config is
what the forge api uses so it's easy to produce .toml files in the same
structure as CC:Tweaked.

All config options and comments from CC:Tweaked are implemented. Some
of these options are ignored in various bits of implementation but that
is another problem :)

Also splits the config into a client and server file. The server file is
saved per-world. Names and locations are consistent with CC:T.
