I was on version 0.28 and got the popup to upgrade to 0.29. I clicked "Later", then I ingested a pcap and quit the app. The next time I opened Brim, I was already upgraded to version 0.29.

We either need to:

1. Allow the user to be on the old version until they click "Update" in the popup.
2. Change the wording to indicate they will be updated to the new version automatically.
3. Remove the popup and simply update them the next time they open the app.
