i've committed this on the 1.6 branch.  this is a pretty significant 
change in behaviour.  before, a reimport would delete EVERYTHING that 
was not explicitly protected by the ".preserve" file of the currently 
active profile.  now, content will _only_ be deleted if it is in the 
"structure" hierarchy so that it will be recreated.  this means that 
removing something from the structure folder and rerunning the import 
step will NOT remove content, you'll have to do so by hand.

i think this is preferable to the other approach, because it was far too 
easy to have everything in your site wiped out; i think content deletion 
should be treated very conservatively.  since this is a behavioural 
change, though, i'd like to get some feedback to make sure this works 
for folks before moving further.  can anyone else who cares about this 
take a look at what i've done and let me know if that works for you?  if 
this works for everyone, i'll merge it into the 2.0 branch and the trunk.

thx,
