[Building Sakai] IMS Common Cartridge import (Also IMS CP import)

[Mark Norton]

I'm not quite sure what you are referring to when you say "site info".  
I'm also not sure where the limits are tested.  Obviously CHS tests the 
limits, but the actual testing may be in deeper, as part of the file 
upload method used.  I was using RSF and the Apache commons upload 
package.  Generally HTTP doesn't care
