Make setting pages less dense without comments for each setting

[hernanmd]

This PR includes two main changes to have better setting documentation in the New Settings Browser:

• Remove explicit documentation presenter below each setting. It makes loading settings a lot faster.
• Better class names for setting presenters.

I like it. It is better than the previous layout but now, it misses the documentation. As discussed, you could define the right panel with newPanedLayoutTopToBottom: and add the documentation at the bottom side + set the position of slider to 80 percent by example.

Yes, step by step :) I will add it in another issue/PR so I don't make this one too big.
