Adds telekinesis to click code.  Fixes issue #1202, #1129, #247.

This adds two atom procs, attack_tk() and attack_self_tk().  attack_tk is used as per attack_hand; attack_self_tk exists on all atoms (not just items) but is similar to the item proc, but without the assumption that it is in the user's hand.

Removes the functionality where entering throw mode would create a tk grab, as it is redundant.

As a default, attack_tk does the following:
* Creates a telekinetic throw for items and un-anchored objects
* Does an attack_hand (paw, animal, etc) for anchored objects
* Does nothing to mobs

As a default, attack_self_tk does nothing.  An attack_self_tk was added to closets to open and close them since that's a common thing.

The following items have added attack_tk procs:
* Fire axe cabinet, extinguisher cabinet, and bedsheet bin will drop into their square instead of putting it in your hand
* Doors only open telekinetically if they require no access
* Chairs will rotate if nobody is buckled to them
* Filing cabinets will remove a paper at random.
* Tables and racks return to prevent telehulk smash

This is INCOMPLETE.  Adding proper TK interaction to everything is something best done in pieces.

In particular, interacting with mobs and items both open up the floodgates for bugs, so we/I need to decide how we want it to go before we commit, and then fix bugs along the way.  Stumbling forward, fixing bugs, and then changing course halfway would be a bad idea.
Bugfixen

Modifies Adjacent() for items, to allow items to be accessed properly inside each other and the user.  This fixes a few bugs seen in testing.
Sets a maximum telekinesis range (in case you were using cameras).

The telekinetic grab now does nothing at all in melee combat.  This prevents double messages where you attack them with the object telekinetically, and then also attack them with the telekinetic grab.

Crayons had a bug where they were drawing at all distances.  This is because in old click code, afterattack() only happened at range when you had the USE_DELAY flag, which is no longer true.  Proper behavior is to use parameter 3 (proximity_flag), which is 1 when adjacent or 0 if inaccessible.
