Restructure

Create global include file called gfx.h which knows about sub-system
dependancies.
Deprecate Touchscreen (GINPUT touch is now working properly)
Merge Graph into GWIN
Change directory structure to reflect sub-system structure
Many small bugs fixed
Split Nokia6610 gdisp driver into GE8 and GE12 controller versions
Fixed broken demos.
GFX sub-systems are now clearly defined and new ones should be much
easier to add.
