Fix spawning bug when spawnlistentry spawn is not enabled.
Create class to wright nbt data to NBTTagCompound from a string format.
Format essentially functions as "tagetTag,TargetTagID,value". Container tags do not, obviously, have a value.
Add some parsing options to ParsingHelper for additional data types.
Add writeNBT tag. Valid for SpawnList and LivingHandler {spawn} tags.
Merge branch 'feature/writeNBTtag' into dev0.9
Closes #48
