Asterix, this method is actually new (i.e., was only in gc before),
but now it is needed (see #1495).  Also, what I was not expecting
was the refresh of self.contact in this same function.  This is
required since the contact goes stale when we go offline.
Not sure if that is a bug or not.

TODO: create 48x48 online and offline pngs for all jabber iconsets

if user removes sth, ask him on quiting about VACUUM and if he likes that do it (sqlite docs say it can take sometime one large db (I cannot test, YANN?) and it is why I do not do it automatically; also fix a bug on massively deleteing contact logs

you can now delete one of more contact logs from database. all should work (else it is a bug) apart from searching which is coming soon

this is a copy of the original, so it should
work

still there are several TODOs
