Add word-wrap option for data labels#493

Specifically on the filtering labels, if you happen to have labels that are “longer than expected”, they are cut off with an ellipsis (…).

It would be very convenient to have an option on the Sorting and Filtering options panel (something like “Allow labels to word wrap”) that added this CSS code (which works).

.wpdt-c .checkbox label, .wpdt-c .radio label {
    white-space: normal !important;
    overflow: visible !important;
}
