norsoolian -- big batch of improvements set 1

[Fred T. Hamster]

make norsoo drivable:

i want to make the norsoolian drivable, like a boat or a plane.
it needs to be a vehicle as well as a pet.

huffpet should report when not near home:

like every 4 hours it could say where it is.
llownersay every hour? or two?
but then also have it instant message every 6 hours or so.
re-use code from stay at home, maybe add that to hufflets first?

pet pointing commands:

face ne, face e, etc. at least this.
or also face a vector?

pet should range in z direction for free mode also.

pet should allow multiple owners, have _OWNER as owners_list.

this would allow chronical to also control the pets.
notecard based so not to infest the script with a bunch of names.

fix norsoolian push boundary condition:

still needs some work.
it's too picky about bouncing people.
allow it to try when slightly farther.
