GPS-reading using Adafruit_GPS module implemented

[Brandnewson]

note that 9600 NMEA is the default baud rate for Adafruit MTK GPS's- this may need to be changed to 4800 if it doesn't work

There is other data that can be extracted from the GPS if needed. Only speed was included in this scenario.

New pins were defined as GPS_RX_PIN and GPS_TX_PIN.

Used this guy's LCD screen display project as heavy inspiration.

Hi @MellingJJ, sorry the long delay, but I've edited the changes recommended. Appreciate the patience :)

@Brandnewson Looking good, have a talk to Cam about getting your code tested :)
