TG Updates r3721 to r3745 Redo

Better changelog will come in the morning! Woop woop!
-

- When an admin uses 'adminwho', they will now also get information on whether
the connected admins are observing (they're a ghost), playing (they're a living
mob) or if they have not even entered the game (they're a new_player mob type)
- In addition when an admin uses 'adminwho' they will see if the admin in the
list is AFK or not. You are deemed as AFK if you have been inactive for 300
seconds = 5 minutes.
- A little code standardization for port gens.

Fix for getFlatIcon runtimes. I think when I changed DamageIcons from a list to
a single image, I may have caused it. Basically, null was getting put in the
overlays var at round start.

Fix for  view-vars refreshing.

- You can now make coffins from wood planks. They cost 5 planks and take 1.5s to
make, you can only make one per tile.

Labcoat buttons are no longer toggle-able while stunned, unconscious or dead.
Fixes  issue 519 .

Disposal update

* You can now Drag-Drop disposal pipes and machinery into the dispenser, in
order to remove them.
* You must now use wrench before welding a pipe to the ground
* You can no longer remove a trunk untill the machinery ontop is unwelded and
unwrenched
* You are now forced to eject the disposal bin before unwelding it.

-Fixed up a bunch more PDA sprites. Added a few more.
-Added a medical belt and a flash to the CMO's locker. CMOs don't have to be
completely defenceless if they want to use their hypo for medicine
- Added an 'equip' button to the old hud (just this one for now) which equips
the item in your hand to the appropriate slot.

- Deleted ERP.dmi
- Moved some objects into /effect
- Removed the debugger object

Welding tool: Mostly code-related, the players won't notice much.
- Welding tool code how has proper comments! Maybe not "proper" but at least I
don't lie and say a proc is/does something that it doesn't actually do.
- Welders now start full of fuel instead of some random amount between 10-20
- Someone decided it would be a good idea to set the welding tool's 'on/off' var
in a ton of attackby() procs. These objects and turfs shouldnt even touch this
variable. This is why people have been noticing their welding being on without
the sprite or damagetype and amount reflecting that.
- - I've removed a bunch of these instances but there are so many objects and
turfs spread out through the code, there's no way to know if I've got them all
(This is the majority of the files)
- - I've created a new proc in welding tools that checks to see if they are
turned on or not. "isOn()"
- - Since I'm not sure if I've gotten every instance of this force-var-on, I've
set the welding tool to update it's icon every process(). I hate adding checks
like this to processes but it's necessary for now.
- Added a setWelding() proc. If you HAVE to turn the welding tool on or off, use
this, don't just change the var. In fact, dont even touch the 'welding' var
anymore
- Fixes  issue 435 

While changing the hundreds(literally) of cases of welding tool uses I've
- Changed some :'s (object:varorproc) I've come across into .'s
(object.varorproc)
- Added checks to make sure the welding tool is actually on before using it
(some attackby()'s didnt have this. Heck, some checked how much fuel you had,
but didn't actually USE the fuel)
- Added sanity checks after some do_after()s that were missing them

Added traitor uplink items back to erro's stat tracker
- Added 'random' with the tag "RN"
- Added thermal meson glasses with the tag "TM"
- Reorganized uplinks.dm a little by moving the 'random' item generation to its
own proc
- NOTE: I have absolutely no way to test this on my own, but it should work!

I've tested a bunch of construction/deconstructions with the welding tool, but
again I've probably missed a few things. If there are any problems, please let
me know and I'll fix them asap.

- Only humans can now use the toggle lock verbs on closets.
