- Added to SImGuiWidget and FImGuiInputHandler handling of touch started, move and ended events.
- Events are passed to FImGuiInputState to be copied to ImGui IO as a mouse move and left button down.
- Added one frame lag between touch ending event and ending processing, to allow ImGui handle mouse-up event.
Moving input state to context proxy decouples it a bit from a particular input source and although not used right now, it allows multiple sources to send input in parallel.

- Added ImGui interoperability utilities mapping gamepad input events to values in ImGui navigation inputs array.
- Added to ImGui Input State support for gamepad navigation inputs.
- Refactored ImGui Input State to keep consistent interface for keyboard, mouse and gamepad updates.
- Added ImGui Context Manager to create and manage ImGui Context Proxies.
- Changed ImGui Context Proxy to dynamically create context and allow pairing with input state.
- Changed ImGui Module Manager to create one widget per context.
- Changed ImGui Widget to work in different input modes.
- Changed ImGui Input State to allow partial reset (only mouse or keyboard).
- Separate modifier keys interface and data from generic keys.
- Cleaned interface to better differentiate between full reset and clearing update data.
- Fixed bug in code clearing characters.
- Added ImGui Input State to collect and store input updates.
- Changed Slate ImGui Widget to handle Slate input events and store them in input state.
