shift-delete: Delete immediately

[Robin Elfrink]

Hi,


I made a small patch that implements 'shift-delete': Delete messages
immediately without moving them to the Trash folder. This helps people
who are over quota and therefore cannot copy any messages to the Trash
folder.

The key_press method of rcube_list_widget simply sets the shiftkey
property whenever a key is pressed.

It works only with the shift key and the del key, not with the delete
button. I haven't looked at that yet, don't even know if it's possible
because my browser seems to handle shift-click it's own way.




Please comment.
