items: rename ItemDropStrs to ItemDropNames

The rationate for preferring Name over Str is that Str
suggest a string for printing and Name a file name,
also based on the following associated PSX debug info:

	char *FileName;
	unsigned char mAnimName;

ItemDropNames correspond to the base file name (e.g. foo) of

	diabdat.mpq/items/foo.cel
