rocky debris is now autominable

You can now mine the loads of annoying rocky debris by just bumping it, be it your mech or your pickaxe, no more need to switch your hands and click every time you stumble onto one. Can be annoying for xenoarches in theory, as miners can shred the archeological sites instantly now.

Please discuss it before merging. If there will be ever a fix for the amounts of rocky debris, you can remove this.
