Added macros to make experimenting with other interface hardware easier.
RAISE_VPP(), RAISE_VDD(), LOWER_VPP(), LOWER_VDD() call their digitalWrite() counterparts.
VDD_ON and VDD_OFF complement MCLR_VPP and MCLR_RESET as a means to change Vdd from active-high to active-low.
Previous behavior remains the default.
Added VPP_BEFORE_VDD define. When true (default), Vpp is raised before Vdd when entering program mode (this is the previous behavior). When false, Vdd is raised before Vpp instead.
I needed to mess with this for my 16F88, probably due to an internal oscillator setting that needed to be cleared.
