Minor Tukushapal Refit

As stated, the changes this mod makes are minimal. It's probably hard to even call it an overhaul. Still, I consider it an improvement over the original.

As usual in my refit series, I fixed all the floaters/bleeders I could find, eliminated all instances of greenlight, edited pathgrids and edited the "Tukushapal" cell lighting settings to be less grey. The biggest amount of work in this mod is probably deleting all the internal geometry that was hidden behind the rocks. The developer probably initially made the shell with velothi pieces, then added rocks everywhere and forgot to clean up afterwards. I don't think this will actually bring a performance improvement but it's still a worthy change imo.

Compatibility: should be compatible with pretty much anything.

Cleaned with TESAME and TES3CMD. Credits to Assumeru (and other code contributors) for the StandardsValidator tool which helped me spot any unconnected/underwater pathgrid nodes.
