4 commits, Kp Ki Kd for each extruder, temp info (command M105) is now no redundant, added the driver´s pulse delay to extend it and also included the Leapfrog Creatr custom board pin asignment.

Created four different commits:

-Rescued the choice for different Kp Ki Kd for each extruder (is not my work just tweaked the code to include it again)

-Temp info was like Extruder_0 Bed and then Extruder_0 Extruder_1 Extruder_2, now is Extruder_0 Extruder_1 Extruder_2 & Bed 

-Added a delay so if a stepper driver needs a longer pulse has it (I have digital Leadshine drivers)

-I included the Leapfrog custom board pin assignment so they can use this version as well
