RadioButtons: Refactor and correct setting sensitivity of other widgets

[ryonakano]

• Create arrays of our own objects instead of Maps for clean data structure
• Have choices in a key of settings in our objects instead of converting label text
  • This frees us from updating getBaseString() when adding new RadioAdws!
• Prefer readable and meaningful variable names
• Use literal true/false because this case the radio button is current selection
• Do not update sensitivity when the radio button gets deactivated because updating should be performed by the activated radio button

(I'm not familiar with JS so might be misunderstanding your code and making inappropriate changes…)

Great improvements! Thank you!I'm going to have to start thinking of this as more than just my pet project if you keep making contributions :D!
