Minor updates
* Changes the README file to add a Sayustation header
* Fixes machines with the holodeck; there was an odd bug where duplicated objects thought they were still in the source area rather than the alpha holodeck.  I cannot for the life of me understand why.  Having them spawn in the correct place instead of moving them afterwards seems to do it.
* Fixes the sleeper console for use with the holodeck
* Fixes the double-wide door; the bound_width was not correctly set, allowing players to pass on the right.  There may be other consequences of being double-wide that I have not yet explored (atmos)
* The actorsuit's microphone icon will be itself now instead of a generic radio.
Refillable Vending Machines & Additional Smartfridges

This is a comprehensive change.  Some existing vending machines have been modified, including path changes.  This will break existing maps, including some away missions.

This addresses several longstanding issues and requests including refillable seed venders, chemistry/virology smartfridge, and insufficient counter space for the cook.

Refillable vending machines are, as the name implies, restockable.  There are sentry procs which can be altered to accept or reject items based on certain properties; you can accept items that are not part of the original loadout, including filling venders from scratch.  These machines are added mostly to assist in reducing clutter in places like the kitchen, theater, chemistry, virology, etc.

Additionally, additional smartfridge types have been added for chemistry and virology.

Map changes include a public food vender for the chef in the bar, and similar machines for hydroponics and the public garden; an empty seed vender has been added to the public garden.
Minor changes

Adds WJohnston's SS21 away mission.
Additional fixes for double-wide airlocks.  They should correctly update airgroups.
Seed bag update

People haden't pushed me hard enough on the seed bags, so I have been ignoring them for a while.  This catches them up, and integrates them with the smartfridge and vending machine.

Seed bags can now be used to fill smartfridges as well as the restockable seed vendor.  Smartfridges can also vend seed bags for removing seeds in bulk.  Additionally, smartfridges in general will load from storage bags, including trash bags.  In these cases it will take the contents on an item by item basis.

Seed bags are biodegradable again.  Shame on me for not fixing this a long time ago.
Minor updates

Emagging vending machines flips the contraband switch, and dumps premium (coin-required) records into the contraband list.  This lets traitors get yellow gloves out of a YouTool with an emag.  Emagging it when contraband is shown will turn contraband back off.  Emagged machines have a tell if you look at the wiring ("Some of the lights are flickering.")

Adds SS21 to the default fileList.txt.

Adds double-wide glass doors to some locations in the station: Hydroponics, Medbay, the Dormitory entrance, and the Memorial Park.  These are about the only possible places they will fit, as there is no vertical double-wide door, and most corridors are triple-wide.
Switches gateway to Ausops' (old) new sprite.

Fixes runtimes for the loot spawner as used in example.dmm by adding sanity checks and conversion code.
Make scythes attack space weeds even when you misclick onto a table or floor

This is to remove the remarkably frustrating case where you set the scythe down on a table you can barely see.
Adds a stack storage rack (AKA shelves).

Like the sheet snatcher, this collects and totals the stacks you put in, allowing you to have a good idea how much of each resource you have.
Renames PDAs and blank ID cards for use with the PTech vending machine.
Teleporter bug fix

You wouldn't know since it never worked, but you were supposed to be able to teleport to anyone with a tracker implant.  That functionality was broken, now fixed.
Minor updates
Timer update

Allows timers to be used in addition to signalers, with anything that uses the wire datum (C4, airlocks, the particle accelerator, etc).

Gives timers a repeat option, so that they can send a signal periodically instead of only counting down once.  Raises the lowest time setting from 1 second to 5 seconds.
Updates changelog.  Fixes small bug.
