[bug] Doors with botched / missing polygons

[Angel]

Several doors in BG2 have botched or missing polygons.  This is broken in both oBG2 and EE.  This is a partial list, I'm updating this as I encounter them.

• AR0406 (Copper Coronet): Door25 has no door open polygon.
• AR0711 (Mind flayer lair under Temple District): Door01 has no door open polygon.
• AR1202 (Firkraag's Lair, King Strohm III's tomb): Door11 and Door12 have open polygons that do not match with the open door graphics.
• AR1302 and AR1306 (d'Arnise Keep L1): Door08 has no open door polygon.
• AR1307 (d'Arnise Keep L2, post invasion): Door02 has no open door polygon (it does have one in AR1303 during the invasion though).
• AR1514 (Spellhold Maze L2): Door15 has an open door polygon that does not match with the open door graphics.
• AR2200 (Ust Natha): StairC and StairD, the stairs to the top platform have travel regions that are way off from their actual location.
