Dogm

I wrote previously that I would review a graphic LCD made by dogm, which was provided by the company so I could update my ST7565 library. These can be bought from Mouser for reasonable prices.

I have made a few changes to my ST7565 library, available from GitHub. Firstly the configuration is now broken out into a new file, so that st7565.h and st7565.c can be overwritten when the library updates without interfering with port settings.
