Upgrade to Meteor 3.0

[jankapunkt]

Hey @nate-strauser how are you? The Meteor Community Podcast is looking for Meteor projects to upgrade to 3.0 during a live-coding series, including talking about selected topics, such as dependencies, technical debt etc.

More on this here:

• https://www.youtube.com/live/G5cqwWhVlx0?feature=share

During this series we could frequently update on a pull request until there is a full 3.0 migration.

Would you be willing to review and maybe even release the upgraded version at the end of the series?

@jankapunkt I would welcome a PR to update to 3.0. Happy to review and release. Thanks!
