Fixed it so the "--help" option works for the crashlog command. Corrected and

filled out the command help and removed unused options.

Updated the command to have a "--load-all" option that will cause the target
that gets created to locate and load all images specified in the Binary Images
section of the crash log to allow for complete program state to be matched
to that of the crash log, not just the images that were in the stack frames
(the default).
