Add a hide/show toggle for the single-window cockpit's secondary displays --
the five MFDs + radar panel (and their button banks) that frame the 3D
viewscreen -- so the player can get an unobstructed full-window view.
- L4VB16.cpp: gBTHideSecondaryDisplays gates BTDrawCockpitPanel (early return
skips the whole instrument composite; the primary 3D view already fills the
window, so nothing else changes).
- btl4main.cpp WndProc: '`' (VK_OEM_3) flips it, edge-triggered on lParam bit 30
so auto-repeat while held doesn't flicker. Handled in WM_KEYDOWN, which the
engine keyboard reader does not steal (it consumes WM_KEYUP/WM_CHAR).
