New command line option: --dont-arrange

Don't arrange the objects on the build plate. The model coordinates
define the absolute positions on the build plate.
The option --print-center will be ignored.

Also there is a fix in the command line invocation of --duplicate-grid
so it will run, but still there is something broken there and the results
are not correct.
