Save optimization settings (not cbot settings) to file

Hi,

Save/load optimization settings would be of great help and I suppose it is a feature that can be implemented with a bit of effort .

At the moment, this parameters get sometimes lost or you have to manually insert on any new instance of the bot.

would be nice to insert this feature also in version 4.1 as many of us use it and in this way we can export our configurations for optimization section to the new version.
