2.7.0

• added alternative mana bar consisting of icons, similar to vanillas resource bars (this first iteration does not yet support multiple icon types per bar, e.g. reserved mana)
• reworked the "naturalManaRegeneration" game rule (now works with mods that display attribute values)
• fixed an issue where the mana bar was empty when joining a world for the first time/respawning
• fixed an issue where the mana bar was visible in creative mode
• fixed an issue where the mana bar was visible even when the HUD was hidden (pressing F1)
