Switch to YAML Config and Make Combat Tag fully translateable

[Techcable]

Combat Tag should have all messages be translatable.
This will fix #3 .

I personally prefer a pretty config with explaining comments over a ugly config without comments.
YAML:

## Combat Tag Configuration ##
# These commands will be blocked in combat
# 'all' blocks all commands except '/ct'
blockedCommands:
  - /home
  - /tp
npc:
  # Despawn the npc after the specified number of seconds has elapsed
  despawnTime: 12

Current Config:

blockedCommands: [/home, /tp]
npcDespawnTime: 12
