* Replace the ServerInput modal with a new dialog based on alf that remembers your server address history and doesnt put staging and localdev in the options

* Update the server selector during account creation

* dont apply capitalization, use url keyboard

* Apply insets to dialog top

* Improve padding of dialogs on native

* Fix race condition in dialog close; also fix fire of the onClose event in dialogs
