Add danger color to #randomize_hash (#2875)

The torrent add dialog #tadd remembers previous settings now to help
users avoid needing to set the same setting repeatedly.

Users also assume that default settings are always safe settings for
general usage, and click through without reviewing them.

A user who checks #randomize_hash for one torrent (deliberately or
otherwise), then is surprised that none of their torrents download
anymore, because #randomize_hash is still checked on all future
torrent additions.

Because users may legitimately want this setting to persist through
several subequent torrent adds, we don't want to remove persistence
for this field. But I think we should draw more attention to its
use, because accidental usage can cause the entire client to stop
functioning as expected (from a user perspective).
