A couple of annoying little problems have been fixed. When
one runs pvs for the first time, none of the databases were
be created, and no error was printed either. This has been
fixed. Now, when downloading files, a progress bar is drawn
and the download rate is also printed, together with the
percentage. This finally enlightens the user on what's
happening on huge downloads. A large number of memory
leaks have also been fixed.
