wikimedia: Add 'case' and 'typeof' to requireSpaceAfterKeywords

While it looks weird, code like the following is valid:

```js
x = typeof'foo';
x = typeof/foo/;
x = typeof[x];
switch ( x ) {
    case'string':
        break;
}
```

More common with parentheses:

```js
x = typeof(y);
switch ( duration ) {
    case( 3600 * 24 ):
        break;
}
```
