Change examine() from an atom verb to a mob verb

Just in time for the feature freeze, a big change that will introduce bugs! Yay!
Mob verb is called verb/examinate(target), which just calls target.examine(user) and face_atom(target)
For explanation why, see http://www.byond.com/forum/?post=1326139&page=2#comment8198716
Long story short, mob verbs are much faster than object verbs. The goal is to make right-click menus populate faster.

Also changes a bunch of examine() procs to always, ALWAYS call the parent. Except mobs, but you have 1 guess why I'm not touching them. Mostly this affects obj/item/examine().
And also remove a whole shitload of pointless set src in view(2) kind of crap. Also span classes.

Thanks Firecage, this is all your fault
Hopefully final pass of object -> mob examine switch
Disregard that I suck cocks

Fixes wrong ignite adminlog message when clicking plasma airlock with hand.
Fixes checks during welding of closets, walls, mineral walls, airlocks.
Updates spiders to have full player functionality
*All spiders can now web turf (but AI controlled non-nurses won't choose to), only nurse spiders can wrap items and lay eggs.
*Eggs laid by a player controlled nurse spider will eventually grow into player controlled spiders, while AI lain eggs will only result in AI spiders
*Adds non nurse spiders to the staff of change as they pass my rules for inclusion (Leaves a corpse, can do everything as a player the NPC can do, can't dominate a round by reproduction)

I take no responsibility for spidercode, it's a bit iffy but as far as I can tell it all works for players now.
more NT ports
reverting a change
Adds step_x and step_y to the locked var list.

Touching either of these on ANYTHING breaks gliding for everything for the entire round.
There is no good reason to ever touch them!

simplifying thermite ignition code on walls. Fixes being able to move around while deconstruction procedures of rwall(replacing sleep() with do_after() ).
Simplifying code and fixing inconsistency with slicing diamond wall ( weldingtool faster than drill/cutter at slicing diamond wall )
missing "return"
* The Space Cube is now generated at world start, before away missions are loaded
This means away missions don't have space transitions
* The setup_map_transition proc is protected from excessive tiles proceeding (the proc is set to the background if too much tiles are processed)
* Added a comment explaining the Space Cube, by Incoming
* Fixes #4903 : "mobs don't maintain momentum on z-level transition"
* Serendipitiously fixes #2614
First iteration of constructable transit tubes
Fixes a mistyped path
