Temporarily Using QB 0.2.0-SNAPSHOT and MR 1.1.0-SNAPSHOT

Note: In order to update MinecartRevolutionTags to MinecartRevolution's new updater api, we had to change the required QuarterBukkit version to 0.2.0-SNAPSHOT, as well as the MinecartRevolution version to 1.1.0-SNAPSHOT.
Using New Updater System

Removed: The old and deprecated MinecartRevolutionTagsUpdater class.
Added: A simple JarUpdater for keeping MinecartRevolutionTags up to date in the future.
