Fixes!

Fixes:

• Tooltip now clamps the position to ensure it doesn't appear offscreen (thanks to npckc for pointing this out! also, check out their awesome dress up MVNA entry here!!)
• Proper find and replace in the text now ensures its surrounded by empty space/punctuation, to ensure only full words are marked up (thanks to the illustrious Feniks for pointing it out - everyone should rank their MVNA entry 5 stars right now!)
