LOTS of changes in this commit...

1. AVC_2014.h: just has a simple waypoint change

2. serial output has been changed so that all serial communications will now be done through the BT serial module and the phone. the only exception is during display_waypoints, the serial output is echoed on the USB serial port so that the points may be displayed and manipulated on a PC

3. AVC_2014.ino: removed the "if(wpr_count >= WAYPOINT_COUNT)" function in the loop section. this function was used to make the car stationary when setting waypoints. HOWEVER, fail_safe.ino has been updated to disable the MCU control of the car when setting waypoint...so the function above is not irrelevant and was removed.

4. CALIBRATION.cpp: added function to cause the servo to sweep to make sure that it actually works on the teensy.

5. DECLARATIONS.h: added void servo_test();

6. GYRO.cpp: serial output to serial BT

7. MENU.cpp: serial output to serial BT. added servo_test() function

8. NAVIGATION.cpp: serial output to serial BT

9. WAYPOINTS.cpp: serial output to serial BT
