Veinminer
- To use veinminer you need to install an enchantment plugin that supports the vein miner enchant.Then you need to configure the veinminer options inside Orestack/config.yml.
Keep in mind that veinminer is still experimental and is disabled by default as there might be problems I didn't find during testing.

- Added vein miner integration

- Added vein miner related options inside config.yml: vein-miner, vein-miner-aliases, vein-generators, vein-size-by-level.

- Fixed an annoying bug which would not let you place a generator when clicking against another generator block.

- Fixed player related PAPI placeholders not working in chatMessage and sendChat actions.
