All Contests - Spacebar and Tab should auto-select both exchange fields

[w7sst]

Summary

The spacebar and tab keys should auto select the exchange field as the user navigates between fields.

Motivation

Improve usability by having consistent behavior on both exchange fields. This also matches current N1MM behavior using the spacebar and tab fields.

Detailed Description

Currently, the spacebar will move between the callsign and the two exchange fields. The middle field (e.g. RST) is selected with the spacebar, but the last field is not selected. This change will provide auto select for both exchange fields. The first field behavior will not change.

Additional context

This change will match N1MM behavior.

Scott, do you want to give this one a try?

As noted in the readme, the Tab key does more than the exchange fields. The space bar just goes between all the exchanges.

I take that back, both tab and space remained in the exchanges during a contest.
