Segway icons.
Just re-created my old segway and made it a hover one.
 Hover Segway code
Just the code for the Hover Segway also comes with a new key included with the icons.

Cargo manifests from CentComm may contain errors.  Stamp them DENIED for refunds.  Doesn't apply to secure or large crates.  Feedback shows up in the orders console, including amount of plasma and crates shipped.  Each entry is preceded by color-coded point value.
Possible errors:
Incorrect station name
Incorrect number of packages in shipment
Items missing from the crate
Changed the health check for crit in life.dm for humans, monkeys, and aliens from < 0 to <= 0.

Fixes that weird issue where people can take 5 laser hits to the face and still run around at 0 health until someone sneezes on them or they stub their toe.
fixed the changelog... could've sworn I pressed reload
removed changelog.html

Well I thought it was game changing :(
Removing the crate-cost from the refund value now uses points_per_crate instead of being hardcoded to 5.
Fixes the bug where clown stamps were usable by anyone, they just didn't affect the sprite.
Also made the stamp check for clumsiness instead of mind.assigned_role.
Acid Damage Fix

Redid a portion of how acid damage is applied. People were not being disfigured when sprayed, and contact with acid for some reason had a 15% chance to do ridiculous damage (~30 per spray puff), otherwise it did very little (~6). It should be more consistent now around the ~12 range per spray puff.

Glasses melt too, now.
Updated object melt probability I overlooked.
Changed all crit checks from static zeros to config.health_threshold_crit

Mech fabricator fix
Mech fabs were looking in their lighting sub-area to connect to equipment in their logical area; if the mech fab and the R&D computer were at different lighting levels, they would cease to be in the same area, making them fail to connect.  This adds a global helper proc to return the contents of a logical area rather than the lighting sub-area.
Makes failing to connect to an R&D computer a recoverable error.
