Change how Block/Item Displays are rendered to how Falling Blocks are

Falling Block entities are rendered just like normal blocks, but for some reason Display entities aren't. The shading on the sides is much darker which make them stand out next to normal blocks. It is especially noticeable on blocks with the cross model like flowers or short grass. Changing them to render like how Falling Blocks are would make them much more usable for builds so they wouldn't look as jarring.
