./update.sh 8 is broken

[SimenB]

Probably from #669?

Running ./update.sh 8 gives the following diff in .travis.yml

@SimenB this probably has not been working for a while. Now the update starts with the template so that's why the other versions are not included. We'll have to find a new way in the script to update only a version....

[chorrell]

Actually, I've been thinking maybe we need to look for a new templating approach. Using bash for this feels a bit cumbersome. Maybe there's a Node.js alternative?

[SimenB]

I'm all for using node instead of bash

[LaurentGoderre]

I think I can fix this fairly easily without switching to node actually

[chorrell]

That's fine, but I'm thinking of long-term. Probably worth raising in a separate issue. Maybe it's just me, but I don't think the bash script approach is sustainable anymore.

I filed #739 RE: alternative templating approaches
