[2.2.0.3] default controller plugin missing Xinput force-feedback

[Paul17041993]

The standard plugin has the option to use the Xinput API for buttons etc, but for the rumblepak options it fails to list Xinput as an option to use. Even with controllers plugged in it lists nothing.

- windows 8.1 x64
- 360 afterglow corded controller

I would assume it's simply a lack of implementation, but it's a little silly to give an option to use an API but have only half of it functional, hence issue more than feature request.

I isn't suppose to be an option in the drop down list, it should just work.
