Final edits to "Vocation and work"

Revised final paragraph to incorporate Horkheimer, Lasch, and Higgins.
Also, added sentence on "The problem of vocations" to first paragraph to
be a bit more emphatic about role of work, since Lasch argues that he
didn't give work enough attention.
Added orphans.txt

Cleaning up main document by adding separate "orphans.txt"
Corrections to "Vocational education"

Major corrections through this section. Last paragraph needs substantive
editing to include Arendt, Ryan, and Rogers. Penultimate and preceding
paragraph need revisions to concluding sentence.
