[Xymon] Hand editing config files

Please add another vote for "don't force a change into what's working so well".

Bruce White's incisive analysis (deleted for brevity) includes what seems to me to be the most salient point: "adding a DB back end might reduce the flexibility to port Xymon to the next O/S or platform"

Thanks for bothering to ask the users, and carry on with the good work.
