Spellbound Update #4

Patch Notes: * Upgraded Spellbound from Unreal Engine 4.13 to 4.15.2. This brings a lot of improvements to performance and lighting. You may notice that the lighting looks a little darker and brighter in different parts of the game. * I figured out a new way to migrate only the game assets I'm currently using in the levels. This means that the package size has been reduced from 9.8gb to 3.3gb. * Fullscreen monitor display: I found a way to display the game play in fullscreen on a monitor. This will help anyone trying to capture gameplay video, stream the game, or otherwise present the game to external viewers. I have experienced a video card crash with an NVidia 970 while recording gameplay. * Bug fix: Casting the arcane missiles could cause a game crash if it targeted an invalid creature.
