relationship beetween metal, crystal and deuterium

[Deenayd]

I think it would be nice to be able to set the relationship of values beetween metal, crystal and deuterium used by the bot.

It could affter both ROI calculations if mines and such AND it could affter how autofarm values potential loot of scanned targets.

On speed unis crystal seems more valuable. For players who don't want to build very high mines metal seems less valuable.

Of course players who decide to pay for an exchange this is probably not an issue.
