made an error in the overhang platforms

WARNING ! DESTRUCTIVE UPDATE !
make a manual save before updating

- removed the build restriction of watertight buildings so they can be placed on platforms
- reworked overhang and skewer platforms so that they fit with that and can't be chained indefinitely.
- reworked the giant sawmill so it is self-stackable.
- skewer platforms are back

Corrected an error in the assembly line
Added back the builder and hauler farm upgrades
Added a builder's variant of the forestry update
The squewer platform is devlocked until i figure out what to do with it.

added ranged district crossings
