Plasma window joins the glass_layout.cfg no-frame list

Browse Source 
The desktop plasma window (L4PLASMAWIN, "BattleTech - Plasma") is created by a
different TU than the per-display panels, so it couldn't be a gWins[] entry and
sat outside the sticky-layout / ,noframe system.  Add a tiny extern-window
registry to L4GLASSWIN so it rides the same glass_layout.cfg:

  - BTGlassLayout_QueryWindow(title, rect, noframe) -- read a title's saved rect
    and ,noframe flag (used by the plasma on creation, BEFORE sizing, since
    WS_POPUP's frame extent differs from the framed tool window).
  - BTGlassLayout_RegisterExtern(hwnd, title) -- register an externally-created
    window so SaveLayout writes its line (with a last-known-rect cache so a
    teardown before the save still preserves the line).
  - BTGlassLayout_Save() -- public save trigger the plasma WndProc calls on
    WM_EXITSIZEMOVE / teardown.

L4PLASMAWIN now reads its saved rect+flag on create (WS_POPUP when ,noframe,
position restored), registers itself, and saves on finished-drag/teardown.  All
BT_GLASS-gated; the pod is untouched.  The plasma blits directly every frame, so
it has no WM_TIMER focus-throttle.

Verified: Release links clean; drag wrote "BattleTech - Plasma=321,222,528,167",
reload with ,noframe brought it up WS_POPUP (WS_CAPTION absent) at 321,222.
