Update c3m3 Nav and Lump

Nav:
- Typical fixes.
- Bots won't fall to water all the time from walkways and shacks.
- A lot of bad connections fixed (like just going through the roof for example).
- Added a ladder to an area where specials have almost no way to get to you.
- Should be a lot less stuckage on the prop_wall_breakables.

Lump:
- Fixed bridge lever prop remaining glowing after being lowered.
- Set bridge lowering speed to 24 from 5 (in order to match the audio).
- Slightly adjusted a ladder to prevent getting stuck while climbing.
- Item density adjustments.
