identifies PWADs lumps shorter than 16 bytes a EDATA instead of ELUMP

[fabiangreffrath]

Because of this seemingly random distinction, deutex -x SD21-Classic.wad fails to extract the COMPLVL lump which contains the string "MBF21", and is thus merely 6 bytes long. This lead to a lot of confusion when trying to debug why Woof would forcefully set a complevel when this PWAD is loaded.

deutex/src/ident.c

Lines 913 to 916 in 870ca04

	if (info->dir[n].size > 16)
	IDENTsetType(ids, info, n, ELUMP);
	else
	IDENTsetType(ids, info, n, EDATA);

I'd suggest reducing the requirement to count as a "real lump" to > 0, in order to keep mere label lumps out of the list of extracted files. Thanks!
