Functional bedrolls (#4874)

# About the pull request

When playing on an event in a seperate server the event runner had
bedrolls we could lay out which made me wonder why we dont have them in
CM! So much like pill packets, with a bit of help here they are
functional bedrolls!

# Explain why it's good for the game

Roleplay is good, i can see many situations where this could be used,
bedrolls around a campfire on sorokyne, making a more comfortable FOB,
pretending to go camping using the new tents, the opportunities are
endless
