Console: move DOSBox IP shift from game pages into game defaults

The per-page "DOSBox IPs (+100)" checkbox becomes a single machine-level
setting per game, edited in Settings > Change <game> Defaults (a "DOSBox
Build" row below Autotranslocate Delay) and persisted in the game's
defaults file (RPDefaults.rpd / BTDefaults.btd) as a top-level
DosBoxAddressShift element.

The game pages no longer carry the checkbox; each RPGame/BTGame reads the
stored default once at construction into a readonly field and applies it
when enabling a pod (MungaGame.DosBoxAddressShift) and when building the
mission egg (MissionAddress). Since it is read at construction, an
already-open game page keeps its shift until reopened -- consistent with
how every other game default behaves.

Verified against vPOD: enabling the DOSBox default drives a freshly
opened game page's pod connection to 127.0.0.101 and the egg to
pilot=127.0.0.101 with no per-page control; unchecking round-trips to
False in the defaults file. All 103 diff tests pass.
