Disable updating old evaluations

Lina has asked me to disable updating of old evaluations to make them
read only. I'm sure a lot of old code can be removed but of now I
thought the easiest way would be to disable the update button.
Update in the Foreground and Version Number

This just moves what we have had at Healthway back up into GitHub as we
have been using Version numbers internally but not pushed them back up
to GitHub.
