Clickable labels for checkboxes

[AC4BB21B]

A lot of checkboxes had unclickable labels, i.e. to toggle them you had to click on the box (clicking on the legend would achieve nothing).

In this PR, I added labels for checkboxes and radio buttons in:

• upload
• bulk download
• security settings
• add friends

On a side note, I tried to conform to each file's indentation (some have 4 spaces, some 2, and mostly some appear mixed). Sadly, Visual Studio Code gets a bit rebellious with mixed-indented files, and my commits aren't as perfectly aligned as they looked in VSCode :/

Aside from the one comment, this looks good to me — and is a great usability improvement. Thank you!

[AC4BB21B]

Actually, I spotted some other forms that I missed in the wizard, mind if I label those as well in this PR?

[ArneBab]

Feel free to do that — thank you!

[AC4BB21B]

This time I think that's it. The unlabelled checkboxes that I still saw are from plugins

[ArneBab]

could you add a newline before .addChild("i")?

[AC4BB21B]

Would it be better like

option.addChild("label",
  new String[] { "for" },
  new String[] { "radioPlugin" + pluginDescription.name })
  .addChild("i", pluginDescription.getLocalisedPluginName());

or rather like

option.addChild("label",
  new String[] { "for" },
  new String[] { "radioPlugin" + pluginDescription.name }
).addChild("i", pluginDescription.getLocalisedPluginName());

or even

option.addChild("label",
  new String[] { "for" },
  new String[] { "radioPlugin" + pluginDescription.name }
).addChild("i",
  pluginDescription.getLocalisedPluginName()
);

I saw a bit of everything around, so I had a hard time picking the favored choice, I rather tried to be more or less the same as what was nearby - unless it was clearly too unreadable, like some one-liners

[ArneBab]

I’d say the second: that is what the code around it does.

Looks good to me — thank you very much!
