NetworkTables updates for beta

This commit does a few things. First, we publish ntcore as a maven
artifact so the plugins can build with new networktables, and java
programs will depend on the correct version when compiled. We also revert
the changes to OutlineViewer for now. I got an exception when attempting
to start a server with the new network tables in OutlineViewer on Windows,
I will create a bug for this. Also, since we don't have the binaries
integrating properly yet and won't for the first beta, we need to be using
the platform agnostic version anyway.
