Rework killicon library
New argument for killicon.GetSize - bool dontEqualizeHeight, set to true to return the actual height of a killicon
killicon.Add can now use .pngs
Added killicon.AddTexCoord - subrect killicons on a single texture (Community Contribution)
Added killicon.Render - draws the killicon without weird vertical offsets, also has dontEqualizeHeight argument to draw unscaled killicon
Changed base gamemode deathnotice to use killicon.Render to have better killicon alignment
