The conflict was that I had modified sdl2.asd to include joystick and gamecontroller
ignoring my plant stuff
Update README.txt

Added psilord to the list of authors
Update sdl2.asd
- corrected all the names of the wrapped functions in gamecontroller and joystick
- added some more of the kitchen sink to the basic test.. probably time to start thinking about some more examples that are looking at specific features
- I didn't change anything, but I think emacs just did a big auto-indent
- added some basic docstrings... need to do more of that in general
- printing out the name of any controllers found in the basic example
- added game-controller-get-joystick
- removed a comment that I don't think applies anymore
- added basic haptic support
- some reformatting because I'm tired of fighting emacs
- updated basic-test to rumble when a gamecontroller button is pressed on a supported gamepad
