Minor update.

[DONE] Overworld Boss Music no longer lingers forever even when you've left their location
[DONE] Revised the UI so that Next Target is clearly not available in the Overworld
[DONE] Static ships no longer go mad (don't ask)
[DONE] Removed old reference to Blind Fury
[DONE] Doubled effects of status changing floor tiles (don't hate me)
[DONE] Ship titles are no longer sellable. NO REFUNDS!
[DONE] Oil level indicator now drawn at same position on ships AND walking player (I'm a pro!)
