Fix various javadoc failures

[FerusGrim]

I'm... I'm really not certain how this could happen, but the javadocs are a complete mess.

/**
 *
 * @author Chris Naude This thread sends player info to linked bots.
 */
public class LinkUpdater {

Your name is weird.

 /**
     *
     * @param plugin
     */

What does this do?

    /**
     *
     */

Could you provide a little more info?

And this isn't just all in one class - it's in every class I've looked through, so far.

Yes it is a mess.
