More Variety in Stroke Assets

Request from Discord (Ally): "The line tool needs more stamps to separate parts of the map, to speed up the workflow and to improve story-telling with the maps.

• The metal bars should be a line stamp, along with the fencing

• There should be another "cleaner looking" brick wall, because the stone walls look a bit too scruffy to be castle/dungeon walls

• Chains would also make a great stamp

• Foot steps would be great for story telling (this is simultaneously a stamp request)

• Creature foot steps like claws would also be nice

• Blood trails also help story telling

• Stairs as a line tool would be great"
