Remove "Press X to cancel" and instead use a "Cancel Button" for login prompt.

Suggested new feature or improvement

When logging into GitHub on the RepoTool the secondary button on the dialog changes to "Press X to cancel" and an "X" appears in the upper right corner.

This is for two reasons

1. No way to listen to the secondary button click.
2. The secondary button click does not fire events with the Task.Delay(1000)

A cool idea to include a button at the bottom of the login dialog with the content "Cancel login". This way, the secondary button text does not need to change.

Scenario

Making cancelling login simpler.
