Demo: Changed demo "Builders" to "Samples".

Browse Source 
Detour: Prefixed static nav with 'dtStat', this includes polys and poly refs too.
imgui: Made imgui code not to use id:s anymore, since there were way too many id clashes.
imgui: Separated the rendering code into its' own file, changed prebaked font to use stb_truetype instead, removed glfont.
imgui: Added 'disabled' property to widgets.
Recast: exposed single triangle rasterization into the recast api.
Demo: Changed the debug draw validation to be "soft", easier to demo now.
