(svn r2024) -Fix: [autoreplace] reverted all changes involving v->set_for_replacement as they caused desyncs.

The bad sideeffect of this is that now no vehicle will automatically go to a depot anymore just
because it is set to be autoreplaced. We will have to find a better way to solve this problem.

Revisions reverted: 1640, 1707, 1709, 1710, 1712(but not the cheat prevention in this one)
