CommonClient: Some GUI polish (#1139)

* CommonClient: Focus text field when requesting input.

* CommonClient: Store and prefill last server address.

* CommonClient: Focus and select portion of server address upon start.

* CommonClient: Don't allow editing of address while connected.

* CommonClient: Don't make pressing Enter in the address bar disconnect you.

* CommonClient: Use TextInput.text_validate_unfocus over jank workaround.

* CommonClient: Fixed hang when closing after failed handshake.

* CommonClient: Made scrollbar wider and interactable.
