Can't type in '=' in PrivateKey field for Interface

[ava1anch9]

The PrivateKey field in the Interface section of the tunnel settings does not allow to type in the '=' character. Therefore, it is now impossible to create a tunnel manually (because PrivateKey always contains '=' at the end of the string).

A workaround found: click the autogenerate ('sync') button in the field to generate a PrivateKey with '=' at the end, delete everything but the '=', and enter the rest of your PrivateKey.
