Epic #72584: sysext:impexp
Missing files during import cause abort
When doing an import and some files are really missing in the T3D/XML file this will cause an abort of the import process as an exception gets thrown. This bugfix wraps a "try" block around the failing method of DataHandler. The default behaviour is not influenced as the exception will get thrown again except if the new DataHandler variable "handleCheckValueExceptionsGraciously" is set.
