- Added SImGuiLayout to resets layout and house SImGuiWidget. - Module manager creates SImGuiLayout instead of SImGuiWidget (eventually it should be replaced with a higher level object, like AHUD). - Reworked ImGui canvas dragging and scaling and moved to SImGuiCanvasControl. - Removed dependency on ImGui internal cursor data. New presentation is cleaner and doesn't use cursor data. - Rendering code could be simplified after layout reset provided by SImGuiLayout. - SImGuiWidget still handles input, rendering of ImGui draw data and activation of SImGuiCanvasControl. - All widgets are in own subfolder.
