Revert "Make use of Composite Builds for OrbisLib"
This will break our build system even further, but
at least allow development to continue.
ForgeGradle 2.x cannot handle composite builds
correctly. As such, we won't be able to pin the
Aether II and Orbis against a specific version
of OrbisLib in our Maven repository while also
allowing developers to work the source code of both
projects at the same time.
We must be extremely careful not to let Orbis and
the Aether II diverge, or both mods could easily
become incompatible with one another.
