[Kst] Tol label updates ?

[Brisset, Nicolas]

Hi,

One of my old requests (I may have put it in bugzilla but I can't
remember) was for top labels (set to the filename and optionally
generated when vectors are imported from a datasource) to be updated
when the datasource changes (Tools->Change data filke...). 
I was wondering whether the new update mechanisms allow to implement
that now. It is a common failure case to be looking at the wrong data
because labels are no longer up to date.
