Peter Johnson f89c5e150f Use new NetworkTables across WPILib (C++ and Java).
Also make sure table listeners stop listening in their destructors.  This
might be better handled by moving the table itself into ITableListener and
providing cleanup functionality there.

A submodule is used to pull in ntcore.
