Pipes bugfix:

- trowing pipes correctly rotates them;
- meters unwrenching;
- pipe dispenser can be unwrenched and pulled, wrench back to use;
- unused pipes can be returned to dispenser;
- Probably fixed bug with non-working connectors;
Windows now are always shown above grilles.
Pipes now are always shown above lattice.
Some other things.
