EXIT GAME on the console screen

,noframe takes the title bar away, and with it the only way out of the
game. The console screen now offers its own, bottom left: half width and
diagonally opposite LAUNCH GAME, because it is the one button on that
screen you cannot undo and it should not sit next to the one everybody
is aiming for.

It goes through the same door as closing the window - fe.closed, so
RPL4FrontEnd_Run returns False and the race loop breaks - rather than
opening a second shutdown path.

Two things had to move for it to make sense.

The saved placement now loads in RPL4.CPP, right after the main window
is shown, instead of only when SVGA16 builds the cockpit. That was not
until a mission started, so the console screen came up at the default
rect with its title bar still on and the window only jumped to the saved
placement once a race began - which, for a flag whose whole purpose is
to take the title bar off, meant it did nothing on the screen you land
on. RPL4.CPP now owns the main window's registration outright and
SVGA16's branches only reload; the reload after CockpitShellProc goes on
still matters, since its WM_SIZE is what re-fits the canvas.

That in turn made the exploded view's position-only registration
incoherent - the startup load had already applied the size - so the
game window is simply position and size everywhere now. The earlier
reasoning that its exploded size IS the -res render size does not hold:
the back buffer stretches to the window in either view, exactly as it
does for the cockpit.

WM_EXITSIZEMOVE moves from the cockpit subclass to RPL4.CPP's own
WndProc, which the subclass chains to anyway. In its old home it only
existed once a cockpit had been built, so dragging the window on the
console screen - the obvious moment to put it where you want it - saved
nothing. There is also a save on the way out of WinMain, for a session
that never started a race and so never ran SVGA16's teardown save.

Verified: on a bare-framed window the console screen comes up at the
saved 1280x760 with client == window rect, EXIT GAME ends the process
with code 0, and a screenshot shows it clear of the column content. A
console-only session dragged to 333,222 900x640 wrote that on the drag,
kept it through the exit, and came back to exactly it on relaunch -
without a race anywhere in the round trip. The noframe and cockpit
round trips still pass unchanged.
