Rework torrent details dialog in Qt client to load from .ui

Make squeeze labels (used for values on Information tab) display tooltip
on hover if their text doesn't fit. Make selective labels (same as in
GTK+ client) text selectable with keyboard in addition to mouse.
Prevent dialog width growth occured before to fit long error texts.
