Changes

Backwards compat

• Added back some missing methods to MixinPlatformManager and GlobalProperties. Fixes ReplayMod compatibility. (FalsePattern/GasStation#10)
• Downgraded Injector's "Delegate constructor lookup failed" error to a warning. Fixes an incompatibility with some intrusive ASM. (FalsePattern/GasStation#12)

LaunchWrapper/FML

• Fixed dev MCP refmap remapping not working. Fixes regression in FabricMC/Mixin@59db546.
  • Reimplemented MCP-to-MCP remapping using the new API.
  • Since IRemapper's contract was changed to accept null arguments, an option was added to RemapperAdapter to handle these with a no-op, emulating the old behavior.
• Fixed Forge mods in classpath FML coremods not getting detected. Properly fixes SpongePowered/Mixin#207.
• Fixed Java agent failing to initialize on LaunchWrapper. Fixes regression in SpongePowered/Mixin@72d0812.
