Added a command that shows how much health left for the specified player (/lifesteal lives <player>)
Added custom amounts for slots in the heart item crafting recipe
Added the info to the console of the adapter's version to help with finding bugs
IMPORTANT:Auto migrations in the configuration file are not yet added, so you need to update your current heart item crafting scheme to the latest structure, or just delete a file/section if you have nothing to lose.
