Fixed bug with removing property from a player using commands
Fixed commands to change properties of _OTHER_ group not taking effect immediately
"&" will now work correctly in remove-strings even after placeholderapi replaced it to "ยง" already
Cutting to 16 characters cuts one more if 16th character is "&" to prevent confusion when seeing it in game
Removed deluxetag yes/no and faction yes/no options from config as they are not needed anymore since remove-strings was added, it just confused people anyway
