allow login using hashed passwords (#4464)

Browse source 
* Support getting a user's password salt via initial websocket connection (added to Event_ServerIdentification)

* Nonsense stuff to figure out later

* move passwordhasher to correct location

* protobuf changes

* add ext to protobuf

* implement request password salt server side

* add supportspasswordhash to server identification

* check backwards compatibility

* reset some changes to master

* implement get password salt client side

* implement checking hashed passwords on server login

* check for registration requirement on getting password salt

* properly check password salt response and show errors

* remove unused property

* add password salt to list of response types
