Declare the g_GameRestarted hack from12f0720f31
in main.cpp, because it is main.cpp and Game.cpp who provide it's value. Move the comment so that the connotation becomes clear when reading main.cpp. Remove the extern declaration introduced to the Renderer infb035d08e3
that became obsolete withed7c66eb82
. This was SVN commit r21816.
