* Added exit trigger action support to XML

* View close triggers don't require an action to be considered valid any more
* Added exit prompt
* Sorted SessionContext to be a smidge more readable
* Added instance fields for referencing to views in SessionContext
* BankNetInteractor now completely cleans its state when Logout() is called
