Created gdisp_fonts.h to describe the internal structure of a font. Moved template directory to templates and created a sub-folder for each low level driver type. Moved the pre-defined font data and emulation code into better locations. Changed the emulation code to be included in the low level driver (where it should be) instead of the high level driver. Added new low level driver gdispS6d1121 (someone please test) Updated and added new readme's.
