Log:
Remove popt references

- popt has been replaced with the GOption infrastructure.
So there's no need to include the popt.h file.
- Also rewritten the comment that was elaborating on popt
vs GOption
- Finally removed the loglevel option (which was excluded from
the compile anyway) that still referred to popt.
