Commit: 63de54bda6aa03295e1b274ebc5bee861eb3d4a4
Author: Pedro Algarvio <pe...@algarvio.me>

GTK UI loading speedup.
Limit the amount of data queried to the daemon to the torrents actually visible
in the torrentview, those that are not visible, won't be queried until scrolled
into a visible position. This speedup together with the chunked session proxy,
makes the initial data requested from the daemon from ~35MB to about ~10MB for
my > 800 torrents. And the time loading it has also dramatically dropped.
