Mapgen: Add global 'decorations' flag
Flag is set by default in MapgenParams The global 'trees' flag remains but is now undocumented and unset by default in MapgenParams Add mgv6_spflag 'trees' set by default in defaultsettings.cpp to affect new worlds only This is automatically backwards compatible for existing worlds
