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

While it looks weird, code like the following is valid:

    x = typeof'foo';
    x = typeof/foo/;
    x = typeof[x];
    switch ( x ) {
        case'string':
            break;
    }

More common with parentheses:

    x = typeof(y);
    switch ( duration ) {
        case( 3600 * 24 ):
            break;
    }
