[Live-demo] Natural Earth in 4.5b2

Hi All-

   I ran a set of tables through st_MakeValid() last night, and was 
reminded of all the numerous, tiny gotcha's that come up
when moving data around. The LiveDVD had just gone 'beta', which means 
not so much thrashing about and changing
things..  put these two together...

   Perhaps the least impact thing I can do right now, is to make a 
single SQL job that loads the new, cleaned tables,
and their geometry_columns attributes, builds indexes and such, and 
stow that on downloads.osgeo.org somewhere.
Then when the LiveDVD script runs, the Natural_Earth shp files are 
downloaded as they were before, but this new
SQL job is run last. As far as naming, an example is  "10m_ocean"  -> 
c10m_ocean. I will leave the new ne_ prefix
for the authoritative Natural Earth set.

   The end result would be the same set of tables and shape files, and a 
new set tables that are clean, next to them.
A README type addendum somewhere, and we have something for this point 

   best regards from Berkelely, California
