To Escape or To Not Escape

This is a small patch, but fixes some issues:

- If you had an emerald saved from the prison, in the hospital you could buy 2 8th floor down elevator buttons, allowing you to skip floor 7

- Removed trades from villagers that weren't supposed to have trades

- Added a sign in the hospital on floor 5 explaining that you have to find 8 buttons (Thanks for suggesting, kaiiguia.)

- Re-added dialogue with Nurse Wolfe in the hospital (How did it get removed?)
