Reading floppies and artifact floppies

[Umbire]

Per this set of lines, Geeks are (probably accidentally?) excluded from being able to properly "read" a pack of floppies:

SlashTHEM/src/apply.c

Lines 3772 to 3786 in d828e64

	if (!Role_if(PM_HACKER)) {
	pline("If only you knew what the heck this is ... ");
	return;
	}
	pline("Due to years of experience with computers, you can read the");
	pline("disks' contents by merely looking at the magnetic surface ...");
	if (Blind) {
	pline("Yet, without seeing, not even you can read anyting.");
	return;
	}
	if (obj->oartifact == ART_NETHACK_SOURCES) {
	com_pager(9999);

The Hacker's Master Boot Disk should also have its own messages when "read" this way.
