Subject: [PATCH] fix empty array elements in command arguments
Adjacent spaces caused empty array elements due to how String#split works.
This change removes those empty array elements without modifying anything else.
Adjacent spaces sent by players are removed in PlayerConnection, so this change doesn't affect players.
But it does affect the console, command blocks, Bukkit.dispatchCommand, etc.
