Title: Issue #204 (Crash when trying to save an empty server)

The onliest case, when app can crash on Add Server screen and cause failure in ../AFHTTPClient.m:232, is passing nil from textFieldUrl while checkServerValidity. So for full confidence it is better to preset all textFields with empty strings in viewDidLoad.
