Added blockbullet ramps to the bottom of the lower entrances to IT and lobby from second, preventing players from losing all horizontal momentum by jumping the moment they enter.
Added blockbullets to gaps around the barrels, sink and crates in IT.
Improved blockbullet between the barrel and crate outside the 2 sewer doors.
The thin indoor pipes leading to upper IT are now only solid to players and physics (pipes and stickies).
Cleaned up clipping on and below the lobby rail, and on the boiler room ceiling.
Removed collision from the computer panels outside 1 and 5 on last.
