- Some performance improvements to JEI recipe resolver
- Use a shared map for upgrade items, meaning we only need one map
lookup.
- Cache the basic upgrade recipes.
- Use the MC version within project rather than version name.
- Add additional maven metadata and strip dependencies
- Shift ICommand registration into the proxy, to avoid class loading
issues. This is probably rather temperamental, but classloading
always is.
