[Signal] More variety for corridors

the new corridors are excellent pieces and fit really well with the new inset furniture for 1-layer interiors, but i find them lacking in some aspects i'll elaborate here

for the standard corridor: overall excellent but limited lighting options. lit junctions would be very appreciated. i have a 3x3 ship domicile that uses one t-intersection and two x-intersections that needs internal lighting and the only way i could provide it was with inset lights in the ceiling - not ideal

for narrow corridors: t-junction, light with no stowage, window. the narrow corridor has some excellent use-cases as a sturdy "hull corridor" (long utility corridors that run down the length of a ship's bow, thnk like those pictures of veeeery long ship passages!) but there's no way to use it for anything but straight lines, unless you use a weaker corridor intersection or half block/slope. if it just had those two pieces as well they'd be perfect

other desirables: armoured narrow corridors with similar characteristics to half heavy armour, possible adapters to willis ducts? really willis ducts could use some expanding as well, vertical shafts would be fantastic (equal width and height, centred)
