Added version output to CraftBukkit that displays on startup.

Add a version display to the startup of CraftBukkit so that we have all
the information we need for support purposes simply by requesting a
server log be pastebinned. I wanted to have it display right after the
official Minecraft version is, but that would require modifying
the server itself.
