* UVs in lightmap density view were shifting after building lighting. Fixed by considering the padding even if lightmap data is invalid
* Auto generated lightmap UV was snapping charts to the whole padded lightmap instead of the actual valid center region. Fixed by subtracing 2 texels from the packing resolution
* Also fixed some merging conflicts of auto gen

The IMPLEMENT_MODULE macro now defines an empty function called IMPLEMENT_MODULE_{ModuleName}, to which we force a reference to via the linker command line. This behavior can be disabled on a per-module basis by setting bRequiresImplementModule = false from a .build.cs file.
