Summary

SUMMARY: Bugfixes "Fix several prying/picking tools bugs"

Purpose of change

Fixes #2130

• manholes and coffins were missing a json field
• when checking for the best items with lockpick/prying qualities, wearable items weren't taken into account

Fixes #1923

• basically what is in the issue, the parameter was passed to the function but never used

Describe the solution

2130

• add the missing json field so that they can be pried open with examine
• remove the check on wearable item
  • you can directly lockpick a lockpickable thing with a worn hairpin
  • you can also pry a pryable thing with crowbar in a toolbelt
