This change allows the user to manually enter an unauthenticated proxy
configuration to be used for all API connections. This is mainly
intended for using Tusky with Tor (via Orbot or a local proxy).
Some things were pulled out of adapters to fragments. New classes were introduced - StatusViewData and NotificationViewData. They not only have view state in them but also help decoupling.
Because introducing parallel model list requires a lot of synchronisation PairedList was added.
Also synchronisation between fragments and adapters is quiet tedious and error-prone and should be replaces with better solution.
Oh, I also couldn’t resist and fixed bug with buttons animation in the same commit.
Although for now it makes no difference calling super.onCreate or not
(the method Application.onCreate() is empty), it is denoted with
@CallSuper and might cause errors in some IDE if it is not called.
