Craftbukkit/Spigot 1.7.2 Support, Simplify Server Started, and Reduce redundancy from shutdown plugin

1.7.2 Support: This will eventually have to be done another way, too many different output expressions (1.6.4 and below, vanilla 1.7.2, craftbukkit/spigot 1.7.2, and forge servers.)
Simplify ServerStarted: The time it takes to start the server isn't used anywhere else, now it just does simple "Done" Detection (which needs to be cleaned up)
Shutdown plugin edits: /save-all isn't required anymore, since it's done automatically anyways.
