[Cuis-dev] [FIX] Handle package scanning errors in PackageInstaller

[Mariano Montone]

Juan, Hernan,


this changeset makes the PackageInstaller handle errors when scanning 
package files.

This fixes the problem with "Missing parserClass preference" mentioned 
in the mailing list.

Also, I think this is the right thing to do.
