Add the ssh URIs to the DEVELOPER file.
Update info about Learning from Alumni in the README.
Delete PNG file with unclear name.
Add instructions to ignore the "current" files.
Update Makefile so that it *doesn't* automatically generate the
subjects.ent file.  (In most courses, I want to be able to easily
drop and add topics.  In this course, that's a bad idea.)
Add outlines/template.sect so that we can turn .md files into .html.
Merge branch 'master' of https://github.com/rebelsky/generic-course

Conflicts:
	README.md

Pulled outlines/template.sect from the generic site, but also had a
conflict in the README.
LfA needs a real subjects.ent, not one generated from a .var file.
Commit all the changes from 2013F (yeah, I'm lazy).
