Multiple fix operations at a time

[Wanderer]

It would be nice if a new option existed in the fix menu, which opened a new dialog, the same as "Settings/Fix Items" in which the user selected all items he wishes to fix for that time only. Initially, the checkboxes should be checked/unchecked according to what is selected in "Settings/Fix Items" but whatever the user selects, when OK is pressed:

1. all those fixes should be performed and
2. the state of the checkboxes in that dialog should be remembered for the session (so, when RC is closed and reopened, they will be again as selected in "Settings/Fix Items").
