Differentiate error msg between broken dataset links and insufficient access

When dragging a dataset from quicksearch results to the canvas, a more accurate error message should be presented depending on the actual problem (either the current user does not have access to the dataset[s] or the dataset[s] are not available (broken link)).
Although mote meaningful error messages are clearly needed, I thought that Kepler currently only shows publicly accessable data in its earthgrid searches. So access limitation problems should never occur? (Dan Higgins)
The case this bug addresses occurs when the metadata (and possibly some, but not all data files) are public and there also exists one or more private data files in the package.
Looks like might have to store individual error msgs in cache? That seems like overkill. Maybe just initial alert when first attempting to read from Earthgrid, then more generic error when retrieving (empty) file from cache.
this is related to bug 3132 in that data download errors are not self correcting.
MessageHandler is being used to display any errors on download. and the errors are self correcting now (cache gets cleaned up if there was a download error)
