MODIF - Program strings (SPrint_P(PSTR())) are now macros to reduce code size and help cleaness

Browse Source 
MODIF - Significantly reduced the code site (down 1k) of enc28j60RegDump() using a macro
MODIF - nicRegDump is now only avaiable in debug mode
MODIF - main's included file moved out of the main.h and into the main sketch
