Allow (auto)fill of partial credentials


it would be convenient if partial credentials would be (auto)filled by bitwarden. If, for example, only the user name is provided, bitwarden doesn’t perform an (auto)fill but only shows and error with the request to manaully copy the user name.

The idea is basically to store only the user name for important/critical accounts and provide the password manually for every log-in simply to not forget it (the pop-up for updating the credentials can be disabled per domain). (Auto)filling the user name would be benefical in those cases.

A configurable setting to enable/disable this feature would be necessary so that a user can chose the preferred behaviour.
