Duncan Wood / UniGraphic

Basically i glued Peter Drescher and Simon Ford libs in a GraphicsDisplay class, then derived TFT or LCD class (which inherits Protocols class), then the most derived ones (Inits), which are per-display and are the only part needed to be adapted to diff hw.

Add  ILI 9320/9325/9328 custom TFT932x class, parallel/spi 8/16bit, with orientation, scroll, pixelread, fastwindow.; Par8 and 16 tested, SPI not at all, needs checking if the CS toggle is necessary (see SPI8.cpp SPI16.cpp).
