Add test case for MinecraftServer remap
Add test case for Bouncycastle

If remapped to obf'd Bouncycastle, but not included in server, then will fail with:

Will succeed if either obfuscated Bouncycastle is available (from vanilla), or if
is remapped to Forge's full version of Bouncycastle included (not obfuscated).
