Correctly set smart dashboard type for AnalogGyro and ADXRS450_Gyro.

The GetSmartDashboardType() function defined by GyroBase was returning the
correct "Gyro", but the overrides in AnalogGyro and ADXRS450_Gyro were
incorrectly changing this, resulting in SmartDashboard not recognizing these
as being gyros.

Additionally, AddSensor in the C++ AnalogGyro was setting the name to Gyro
rather than AnalogGyro.
