New things in this release -
GuiDropDownList is in, which mean the gui system is finally complete!
Key repeat functionality is in.
I finally fixed the collision bug where two collidables would sink into each other without permission.
A LOT of refactoring happened. Hopefully I didn't break anyone's code. I think Buttermilk's API is coming to a point of maturity where these things won't happen so much anymore.
Certain things that didn't get done for 0.1.9 that I wanted. There's still the issue with 3d objects changing size somewhat among different resolutions and OnCollision still not having a normal. All in due time.
Texture bleeding has been fixed. It now uses an "inset" of one pixel (by default) for all textures. So make sure your art reflects this as well.
Add / RemoveComponent has been removed. Now you change the parent / child relationship of gui components by simply using the child's Parent property.
Anyways, this is a good release. Have fun!
