Mainly item and structure fixes

• Updated title for 90 NS as the old one was not very good.
• Added rarity to the items text (and hover text) in mail receive screen.
• Tower guards should now be more responsive when spawning.
• Corrected some size values for seals that resulted in a larger yield of hides then intended. Should now yield 2x 6kg hides instead of 2x 15kg that it did before.
• The fungus spell should no longer be able to spread mycelium to cobblestone tiles, and possibly other unintended types as well.
• The valentine flowers should no longer turn into a marble planter when decaying.
• Bracers should no longer hide shields when equipped, and will for the time being not be visible at all (the bracers not the shields).
• Fixed an issue where the examine message for soup would disappear when splitting the soup into new containers.
• Changed it so that Bulk storage bins no longer delete partial items when removing items from it.
• Examining a timber framed door under construction should now show the materials needed to finish it.
• Plain stone doors should now properly be shown as options when the house you are building requires a door and won’t let you build anything else.
• Fixed an old bug where it wasn’t allowed to build upper floors on deed perimeter north and west of a deed when the structure was just outside of the deeds perimeter.
• A rope is now part of the newbie toolset.
