Double agents can now be picked for late joiners.
This works by keeping a list of players who are applicable for double agents and then after a certain number of them are picked it will tell them all to kill each other.
Increased the amount of double agents that start in the round (x1.5).
Added checking for the other awaiting agents, to make sure they are still alive, human and not disconnected.
adds more "complete" food, using the unfinished feeling food (such as fried egg, sausage etc)

New AI Status icons, Sal and Hal 9000

As SS13 is the game of references and if the voice announcement gets
added then a nice Sal 9000 would be nice. I also thought to add Hal
after as Hal is awesome.
Wrong color for Sal

Sal 9000 is a Blue glow, Not purple.
*updated beans sprite
*adjusted recipes to reflect suggested ingredients
*graphical update, changes to shading and colors.
Small fix.
Update for power code to remove some bugs and fix some functionality
Functionality
========
*Cables can now be placed across each other and not connect, just like cables placed in the map editor.
*Alternately by leaving a "node" or "dot" in both cables you can have these cables connect

Bugs Fixed
=======
*Unconnected cable networks which share the same powernet and power are no longer created when adding cable to nodes or removing nodes on top of smooth cable

Code changes:
==========
*Adds denode proc that should be called when a wire is added to causing it to no longer be a "node" (i.e. terminates in the centre of the turf)
*Adds propagate_network proc that traverses the graph adding every cable to a new network while removing the old one
*Adds call to denode in the cable_join proc
*Fixes mergeConnectedNetworksOnTurf() to only connect cables that are both nodes
*Adds a get_marked_connections() proc to cable which finds all edges connected to it's endpoints regardless of whether they have a powernet(as opposed to get_connections())
 * Small fix to the modifier changer.
clarified a comment
creating a get_marked_connections method for machines that doesnt check for powernet==null
making propagate_network non recursive
-Fixes issue 1462
Adds an update icons call to cloakers

-Fixes issue 1387
Clonees get healed of all damage types while in the pod.
Adds a plasma counter hud for aliens that works similar to the changeling's chem storage and blob's resource storage counters.
Instead of overall health, clonee ejection is based on cloneloss. This eliminates the need for healing (inaprovaline is still injected otherwise they'll die of choking since they start in crit)
Moved plasma counter to right.  Flipped sprite for it, named Power Display2 in screen_gen.dmi
Updates the paths of all away missions
Merge remote-tracking branch 'upstream/master'
