Et Futurum Requiem

Notice: Interpolated texture support will no longer be built into Et Futurum Requiem as of this version. Visit #467 for more information about what that means. NotFine or Angelica will be required in the future to use this feature.

• Removed interpolated texture icon support
• Update boat textures to use the pre-JAPPA style (thanks DarkBum!)

Contributions by @KAMKEEL:

• Added thin glass panes/bars (when not connected to anything, the pane/bar is a thin pole instead of a plus shape)
• Fix moss having pathfinding issues and wrong material
