Add functionality to swap between doors

[CHamilton0]

• Need to be able to choose the door that is being opened
• Can use a button to switch between the doors
• As well as a text element that says what door is selected
• Will send a different activate door web request based on what is selected
  • Server will handle both the doors, so no need to switch doors on server, just change what is sent
• Need to update state checking for both doors
