Second screen: fit the cover, scroll the panel, mark hardcore vs casual

The cover was CENTER_CROP in a grid cell. Box art is portrait and a cell is
not, so filling the cell ate the top and bottom of the cover -- the parts
carrying the logo and the title. It fits inside the tile now and letterboxes
against the tile background.

The panel root could not scroll, which was survivable while the tile list was
short and stopped being so the moment four more tiles were added to it. The
panel has no say in its own height -- the user chooses how many tiles and how
tall each one is -- so anything that did not fit was simply clipped off the
bottom of the display with nothing to say it was there.

"12/40" did not say whether those were earned in hardcore or casual, which is
the distinction RetroAchievements cares most about. The counts now carry
marks for both. rc_client reports a per-achievement mask where a hardcore
unlock also sets the softcore bit, so the casual figure is the softcore-ONLY
count rather than the total -- otherwise every hardcore unlock would be
counted twice.
