Reset button should send a close pada command

[jeffstjean]

In the new messaging protocol (which is yet to be implemented), there will be an ACTUATE_GROUP command that will allow us to actuate all the servos associated with DROP_PADA. This new protocol will come with a change to the /command endpoint. Instead of the payload looking like:

{
    commands:
    [
        { 
            command: 'DROP_PADA', 
            args: []
        }
    ]
}

it will be like this:

{
    commands:
    [
        {
            command: 'ACTUATE_GROUP',
            args:
            [
                group: 'PADA',
                state: 'OPEN' 
            ]
        }
    ]
}

This will allow both OPEN and CLOSE states to be sent for a given servo group to open or close that group. The backend hasn't been updated for this yet but I have created a branch feature/message-0.5 where all these changes can be made. Branch off of feature/message-0.5 into a new branch feature/message-0.5-frontend and make a PR back into feature/message-0.5 when complete. The backend changes, when complete will be on feature/message-0.5 and can be rebased onto feature/message-0.5-frontend to test everything. In the meantime, modify api/routes/CommandRoute.js to print out the req.body to confirm the frontend is sending a properly formatted request.
