Repaired simulation build on linux

Browse Source 
Reverted to old driverstation and joystick code because we're not ready
for windows drive station yet

updated paths to reflect new wpilib organization
fixed name of gazebo topic (if you want /gazebo/frc/time use ~/time)
included network tables in wpilibJavaSim
Added ds script, and improved frcsim script
always start gazebo with verbose
