Changes:

• ImguiContextWrapper renamed ImguiState
• ImguiState is no longer a tuple, instead a struct
• Added ImguiStatePtr for shorthand of the Arc Mutex type.

Fixes:

• Indices data was incorrect, causing extra polys to be drawn, resulting
  in malformed windows in some cases with some fonts.
• Now supports imgui::Image types with amethyst textures. See the
  demo_custom_texture for details.
