Zdoom does not recognize the extended lump in Blasphemer iwad

[Cacowad]

Or a similar cause probably, the effect is that you can't select episodes 4 and 5. Before you ask, vanilla heretic.exe and chocolate-heretic does not have the same problem, they recognize the episodes just fine. that's why i think it is a zdoom specific issue. Tested in zdoom 2.7.1.0 and 2.7.9999.0

IWad
{
	Name = "Blasphemer"
	Autoname = "blasphemer"
	Game = "Heretic"
	Config = "Heretic"
	Mapinfo = "mapinfo/heretic.txt"
	MustContain = "E1M1", "E2M1", "TITLE", "BLASPHEM"
	BannerColors = "73 00 00", "00 00 00"
}

IWad
{
	Name = "Heretic: Shadow of the Serpent Riders"
	Autoname = "heretic.shadow"
	Game = "Heretic"
	Config = "Heretic"
	Mapinfo = "mapinfo/heretic.txt"
	Compatibility = "Extended"
	MustContain = "E1M1", "E2M1", "TITLE", "MUS_E1M1", "EXTENDED"
	BannerColors = "fc fc 00", "a8 00 00"
}

IWad
{
	Name = "Heretic"
	Game = "Heretic"
	Config = "Heretic"
	Autoname = "heretic.heretic"
	Mapinfo = "mapinfo/heretic.txt"
	MustContain = "E1M1", "E2M1", "TITLE", "MUS_E1M1"
	BannerColors = "fc fc 00", "a8 00 00"
}

Notice how the HSOTSR IWAD gets a "compatibility = extended" line that Blasphemer and plain old Heretic do not have. Adding it is all that's required.

Welp, that was quick, i'll modify my version of the iwadinfo.txt and post the procedure on the BM github page while we wait for a official release from the zdoom mantainer. Thank you for this piece of information.
