This small patch deals with collision issues with bookshelves, items tend to float if they are on the third shelf of a bookshelf. I found this to be a huge issue when decorating, if you find anymore you need fixed let me know and I will fix them. This will evolve into some bug fixing for bookshelves as well, like activator lock up and triggers going away etc.
Fixes collision for: 0.2 - Proudspire Bookshelves - Breezehome Bookshelves
0.1 - Honeyside Bookshelves
Let me know if you find any others needing to be fixed.
