Release 4.12.6

Seven commits since 4.12.5, all about where things sit on screen.

RP412MFDLAYOUT remembers window placement across the menu-race-menu
loop, in mfd_layout.cfg beside bindings.txt: the game window, the
exploded view's display panes, and the plasma glass. Append ,noframe to
a line to take that window's title bar and border off - a cockpit
filling a monitor edge to edge at a rect you chose, where -fit could
only do it by taking the whole screen.

That needed a way out of a window with no title bar, so the setup screen
carries an EXIT GAME button, bottom left and diagonally opposite LAUNCH.

The Steam host/join buttons dim and say STEAM NOT RUNNING rather than
disappearing - two buttons quietly missing reads as a broken build.

And the Winners Circle camera is framed off the award stand rather than
off whoever is standing on it. It had been averaging the filled spots,
which moved the shot with the head count: eight finishers put the eye 24
units closer to the stand and aimed it at the middle of the tiers
instead of at the winner. The framing constants are untouched, so the
shot everybody gets now is the one that was dialled in.

Version strings bumped in RPL4.CPP, pack-dist.ps1 and the controls page
that ships in the zip.

Built clean, packed, and smoke-tested from the dist: boots to the
console screen reporting 4.12.6, virtual RIO up, Steam transport up,
nothing alarming in the log.
