New script which parses raptor logs directly to produce a BRAG summary. New version of XML structure accommodates causes of failure as well as the effect of the failure, and deals with excessive error messages. New structure also avoids a potential problem (bug?, questionable feature?) that both IE and firefox exhibit. Some simplifications of brag utilities module.

Moved common code to shared module.

Updated the options to pass to getenv, to include -k. This avoids aborts if things are not exactly as the tool expects.
