Since the `border: 0;` property is applied
to every checkbox, there is no need for a class.
This is also a good opportunity to use ternaries
for the `checked` attribute, instead of clumsy `if`.
This commit should fix the following javascript crash that
may occur if the localstorage isn't available/supported by the browser:
```
more.view:140 Uncaught TypeError: Cannot read property 'playCountValue' of null
at loadShuffleForm (more.view:140)
at HTMLDocument.<anonymous> (more.view:181)
at n (jquery-1.7.1.min.js:2)
at Object.fireWith (jquery-1.7.1.min.js:2)
at Function.ready (jquery-1.7.1.min.js:2)
at HTMLDocument.B (jquery-1.7.1.min.js:2)
```

For convenience, shuffle radio filters were saved and restored when
loading the `more.view` page. This also happened for the `_csrf` field,
which caused it to take an old and invalid value.
