Keep world as in UQM

[GoogleCodeExporter]

Every modification to the code should preserve the original world. That means 
random numbers need to be tested against the same values, or shifted if tested 
against a RESOLUTION_FACTOR dependent value.

A critic example of this as of revision r180 happens in system generation : 
planets and moons are not the same in uqmhd and in vanilla UQM. First I thought 
it was due to SCALE_RADIUS and its companions (and they did have an influence), 
but there seems to be something else I can't put my finger on.

Problem solved in r181, the additional EARTH_WORLD was messing with the choice 
of planet types. Special world types should be added at the end of the planet 
types enum and of planet_array.

Issue remains as preserving the world has to be kept in mind.
