Change the launcher icon back

Look I get it that the Creeper is iconic for Minecraft...but it makes a TERRIBLE icon for the game.

The grass block is known, instantly recognizable to an even greater degree, and has been the logo for over a decade. Not everything has to be 'refreshed' every few years, despite what the boorish techbros might think.

Leave well enough alone, and don't fix what ain't broke.
