Adding support to BlockTextPromptAlertView textField delegate using block
Improved reliability to BlockTextpromptAlertView

When calling show to BlockTextpromptAlertView in some cases and
devices, the AlertView didn't go up and stood behind the keyboard. So
instead of using an NSTimer to trigger to the TextField
becomeFirstResponder, now it's done via NSNotificationCenter from the
animations completion block from the superclass BlockAlertView.
