Consider using Stonecutter to enable multi-version development #142
Description
Currently you have multiple Git branches for each Minecraft version but it can be complex to maintain differences between versions.
Stonecutter is a Java pre-processor that allows you to conditionally change code at runtime within a single project as it dynamically generates the version specific code when required.
