Credit to an Anonymous Person for helping me come across these things.

Fixed /nv reload to reload both "messages.yml" and "config.yml" instead of just the "config.yml" file.

Added two bypass configurations for nightvision itself or all potion effects to the /heal command from essentials.

Renamed most things in messages.yml as well as added some.

Added nodes: nv.heal and nv.heal.others to the plugin.
