[Apiman-user] Updated a bunch of Apiman UI dependencies on master -- testers appreciated!

Hi All, After battling with the JS ecosystem's dep nightmare for much of today, I've managed to get update several UI dependencies on master -- things *seem* to be working as anticipated (after juggling a few incompatibilities around). This was necessary because some deps are quite significantly outdated and we need to move to more modern ones to ensure maintainability, security, etc. However, there's still a high risk of breakage, so if anyone can try things out it would be greatly appreciated. Quick Instructions: 1. Check out the main apiman repo. 2. Run Apiman in your usual way. 3. cd to manager/ui/war 4. yarn install 4.5 you may need to modify apiman/config.js for your setup 5. ./node_modules/gulp/bin/gulp.js 6. Navigate to http://localhost:2772 Regards, Marc
