[Courses] [FS] Finally, addressing those symlink questions

[Meredydd]

I've tried to answer as many of your questions about symbolic links as I 
can, and ended up writing an entire new lesson. So it goes...

New lesson:	Lesson 2 supplement
Topic:		More on symbolic links

This supplement attempts to answer the questions raised over the 
discussion of symbolic links in Lesson 2

URL:			http://www.linuxchix.org/content/courses/filesystem/Lesson2.html

Buffer:		0.25 lessons - I've taken time out from L3 to write this
			supplement, please keep poking me...
