Subject: [PATCH] Micro-optimizations

- PluginManager.dispatchCommand() avoids regex while splitting commands. Java 7 introduced an optimized String.split() that should be used instead (affects command dispatch).
- Don't attempt to format arguments when there are none provided
- Don't create a data input stream for every plugin message we get from servers
