[K12OSN] Beta Fl_TeacherTool 0.71 for K12Linux (LTSP5)

[Jon Williams]

It looks like I missed the configuration change with the
/opt/ltsp/i386/etc/ssh/sshd_config file.  I thought I was being pretty
meticulous but I missed that step.

Something still isn't right however in that I had to set
PasswordAuthentication to yes instead of no in order to get the tool
to come up.  But at this point I'm able to remote in and control my
thin client's sessions so that's progress.  It's also about 1000x
faster than iTalc so I'm pretty happy.
