TO: Type validation for steering targets

[moltzaum]

POST /api/1.1/steering/:id/targets

{
    "targetId": 8,
    "typeId", 7,
    "value": 100
}

This endpoint doesn't perform validation on the type id. The only valid types are STEERING_ORDER, STEERING_WEIGHT, STEERING_GEO_ORDER, and STEERING_GEO_WEIGHT.

I came across this while reading the documentation, where the HTTP type is used.

The description for 'value' in the documentation shouldn't correspond just to the weight, but to any of the types that are posted.
