Undo: use QUndoStack::isClean() to determine unsaved changes
Properly implement the unsaved-changes flag(s). Since we currently have
two kinds of changes, there are two flags:
1) dive_list_changed in divelist.c marks non-undoable changes. This flag
is only cleared on save or load.
2) QUndoStack::isClean() is used to determine the state of undoable
changes. Every time the user returns to the state where they saved,
this flag is cleared.
