Add owned usernames screen

[rachelhamlin]

From the main screen of the DApp, user should be able to access screen 20_02 to see a static list of their owned usernames.

We did not build anything to support this. There are multiple possible implementation routes but nothing we have explored in detail.

@bgits what do you mean, to support lookup of a user's names, or UI for it?

[bgits]

We don't have a reverse lookup, given an address or contact code get registrations. Most likely the best approach is to build an indexer, a couple approaches possible here including maintaining a REST API to allow such lookups.

Okay, noted. So we'll remove that block of text from the main screen for the launch.

It's not possible to reverse multiple domains to the same ethereum address.
Reverse lookup will always find only one name.
Reverse lookup exposes user names.
Recommend use browser storage for saving that information and showing to user.
