Jams the three devices that I'm aware of that use subspace communications: Headsets, PDAs, and Communicators.
All three will be unable to communicate if in range of a jammer. The default range is 7 turfs, the battery that comes in the jammer is a weapon cell (just to make it a little harder to find replacements) and lasts 60 seconds. The range and power use are variables.
Speaking through a headset will produce 'soft' or 'loud' static depending on how far you are, allowing you to sort of dead-reckon your way to a placed jammer. You can just carry them, otherwise.
I've got no experience with adding tator items so I'll leave that sort of thing up to you guys.
A lot of new defines are now in inventory_sizes.dm, which contains;
All the size identifiers (the thing that tells the game if something is bulky, or w/e).
Storage costs for all the sizes, which are exponents of two, as previously.
A few constants for inventory size.
Also changes all storage item's capacity definitions by basing it off of how many 'normal slots' exist for it. This allows one to change the definition for all of the defines in the file, and everything will follow along without needing to change 500 files. In testing, I made all ITEMSIZE_COST_* defines doubled, and nothing had broke.
The benefit of doing all of this is that it makes adding new weight classes in the future much simpler, and makes knowing how much space a container has easier, as seeing ITEMSIZE_COST_NORMAL * 7 means it can hold seven normal items.
Adds a new machine to telecomms, which contains special PDAs corresponding to each department on the station. Sending a PDA message to one of these PDAs will duplicate it to everyone in the department the PDA is assigned to. It determines what department someone is in by cartridge type.
Adds cartridges for several jobs that were missing them, for the purposes of being recognized as being in a department. The cartridges otherwise do nothing.
New circuitboard to build the new pda multicaster. It can also be deconstructed with the standard machinery deconstruction steps of screwdriver > crowbar.
