Ion laws (including the "random" ones by admins) are now more visible for the AI/robots.

Because single line of text is so easy to miss in spammed chat. Now it automatically shows output of show-laws verb which is significantly harder to miss.

Changeling Fix
- Fixes #7550 and one other bug which is not on issue tracker
- Uncomments one line of code which caused #7550, considering reasons for this being commented out no longer apply. (parasting is no longer cheap OP ability you have from start) Changeling rewrite is probably going to occur soon anyway.
- Removes one line which caused bug with "Absorb" ability - victim was immediately absorbed after the "You stab the X with proboscis" part, instead of waiting few seconds as it should.
