Add tooltips to each device

[virtuald]

pyfrc enables this functionality via sim/config.json. It's not super extensible -- so we should change the JSON so that its usable from both pyfrc and websim. Right now, all pyfrc data is read from the 'pyfrc' key -- websim should not do this, nor should it have its own key.

A sample configuration?

{ 
    "joysticks": {
            "0": {
                "show": true,
                "axes": {
                    "X": "Strafe",
                    "Y": "Back/Forth"
                },
                "buttons": {
                    "1": "Reverse Direction",
                    "2": "Can Down",
                    "3": "Can Up",
                    "6": "Can Top",
                    "7": "Can Bottom"
                }
            },
        }
       "pwm": {
            "0": "Left Front",
            "1": "Left Rear",
            "2": "Right Front",
            "3": "Right Rear"
        },
    }

I'm not convinced that it's totally a good idea to do it this way, I'm open to something more flexible.

Websim currently doesn't have any tooltips. Do you think the websim and pyfrc sim need to share the same config @virtuald ? Currently the config is under its own "websim" key, the naming is different (e.g. "w" is "width", "starting_x" is "startingX"), and I plan on it having plenty of physics related configuration options the pyfrc sim does not have.

For settings that are the same, it seems that it would be nice to have them match because backwards compatibility?

Do you think the configuration should still be under "pyfrc" for the sake of backwards compatibility? I guess I should allow for both "pyfrc" and "websim", that seems to make sense to me.
