Dan Ghiciulescu / LCD4884

Updated library to work with the FRDM KL25Z board. Original code downloaded from DFRobot. Warning. For the 5 way switch to work correctly the LCD4884 shiled needs to be modified. The PCB line between resistor 202 and 102 just bellow the RED power LED needs to be cut and a connection from the 202 resistor to the 3V3 pin needs to be made.
