Add ImGui input controls for plugins (#1182)
Add bindings for ImGui input functions. This will at least let plugins do some basic input instead of checkboxes and buttons. Rearrange files for the imgui project to `inc` and `src` - will probably do this for the rest of the projects at some point too. #1129
