Bug 263.
Changed oh-so descriptive function names of 'phase_one' and 'phase_two' to
'print_course_creation_page' and 'create_course'.
Rewrote html for course creation page.  Now user must specify a home server
for a course.  Suggestions on determining a default server would be appreciated.
When creating a course, now deal with course_home form parameter and pass it
to lonnet.
