I'd like to try upgrading rather then pinning first. (I'll make the pr now)

For the 1-10 release branch at least we can't upgrade: Flask-Admin hasn't yet published the fix pallets-eco/flask-admin#1951

Lets merge this one and push it out, then I'll look at unpinning/upgrading all the deps as needed on master to update it

I think no matter what, it's safer to downgrade werkzeug for 1.10.x rather than upgrade flask.

Oh FAB is broken too because of it's dep on flask-babel<1
