Log Message:
-----------
-> FLT import bug  (loose vertices)

New faceweld code broke the import of meshes with loose
vertices. Also added exception handling to the importer
and exporter so that UI doesnt quite when errors are encountered.
Instead traceback is printed to stderr and control returns to
the script UI
