Geremia G / SPI_TFT_ILI9341_fork

Forked from Peter Drescher lib, using always 16bit spi, init values for chinese red pcb, added read cmds and some mess here and there

Fork of SPI_TFT_ILI9341 by Peter Drescher

always 16bit spi for speedup on slower cpu, added read id, read status, read pixel, other stuff i can't remember

Who changed what in which revision?
