the Sliver object needs a setter for the approved parameter

[chaos@bbn.com]

Right now, there is no setter for the approved parameter of the Sliver class. I can set it directly using:

sliver.approved = <value>

but that doesn't provide for any value-checking.

This works now. It rejected my initial submission because it was type string (the string has the value "True", which might be worth accepting, but imo isn't work worth worrying about right now). Now this:

  print slivers[sliver].approved
  slivers[sliver].approved = bool(sinfo['approved'])
  print slivers[sliver].approved

yields:

False
True
