SelectAll except n rows

[ghost]

Hi, great work here. I've found an issue with the select all button For instance, I want to remove all my users except myself using mass actions: I use the selectAll button to select all my rows and then I uncheck the row I don't want to delete. When I execute the action, all my rows are deleted (even the row unchecked) which is quite annoying.

I saw in the Grid.php class that when the variable $actionAllKeys is set to true, the array containing row keys is empty. I understand the complexity of getting all keys of the table and that's why i want to know if someone here have a fix for this.

Thanks !
