Add button "Select all values" in widget filter with operator "is any of" and list

[GaetanPRU]

Add a button "Select all" in widget Filter when we use operator "is any of" with a list. We have reset button after we selected many values but not the possiblity to check all found values.

When user search a value in the list, he has to check every box one by one. We have this option in Dashboard on category selector and it's very useful.

Thanks
