are Exploitable without it) and fixes #8959.
Fixes an it's -> its case in Icecoon's Weapon Pack mod.

Fires generate hot air
Hot air created by fire lingers longer, and has more strength levels
Handheld game fix.

Fixes https://github.com/CleverRaven/Cataclysm-DDA/issues/9061.

Stethoscope spawn expansion.

Fixes https://github.com/CleverRaven/Cataclysm-DDA/issues/9060.

Adds stethoscope spawns to hospital_bed and hospital_lab groups.
Gives trowel digging quality level one.

Category fix for bike helmet.

Other soups.
Switch to using argparse. Update pluck to use argparse and multiple where arguments.
Convert count_values to allow multiple where cases and use argparse. Fix a bug in the primitive matcher that wasn't friendly to booleans. Still uses regular expressions, but also switch to match instead of search to make things stricter.
Get rid of list_values. Not necessary. Count values should allow for distinct output, but easy enough to do witha a complimentary script at the moment.
Sheet.
Towel.
