Please, sir, can I have some more...half passages!

Added:
- Half Passage Corners
- Half Passage Pillar (Left and Right, to connect to the corners or to just make central pillars)
- Passage Pillar (Just the top/bottom with a corner)
- Half Passage Air Vent (Fill your massive passages with sweet sweet Oxygen)
+ As always, large and small grid, and lighted varients (except the Vent)

Tweaks:
- Adjusted all doors/airlocks to better match Keen's supercharged door speed and sounds
- Changed mod catagory from "AVTech" to "+AVtech" (with other changes) so that it appears below Keen's catagories

- Split Half Passage Door to Left and Right to handle airtightness properly.

- Changed speed of Passage Airlock to better match sound(ish).

- Adjusted Enclosed Passage Airlock components to match non-enclosed version.

- Fixed Lighted Enclosed Passage Extention missing floor

-Fixed issue with airtightness on half doors
