configure_input: Modernize and cleanup input configuration tab
* Removed use of raw QTimer* pointer. * Update to use type-safe QObject::connect. * getKeyName can be a static local function. * Prefer to use function arguments instead of member variables. * Store Qt::Key instead of converting string back into keycode.
