[pmg-devel] [PATCH yew-comp 1/1] login panel: make realm selector optional

[Dominik Csapak]

in some cases, we don't want to have a realm selector because the user
has to enter e.g. an e-mail address instead (like the PMG mobile
quarantine gui).

Add a property for that that defaults to the current behavior and add a
validator for the username field that checks for an '@' in the middle.
