Don't upload to maloo by default

- Main change is to invert meaning of -l flag. It now turns *on* uploading
  logs to maloo, instead of disabling it.

- Also added check to find the absolute path for maloo_upload.sh, just like
  we do for the test scripts we run.

- The verbose option now dumps the output of the script to the console (and
  also saves it to the log file).

- The -h (help) option will now page the help text if needed.
