URBNG-440 [Android] Make dialogs look like UX specification

Dialogs ready..

If I have not found dialog in some class and you notice that, please leave me a note.

They work even better than old ones - COOL layout (android < 3.0 noticable).
Dialogs not dissapearing on orientation change.
Easy to migrate from AllertDialog.
They bake cookies. (it's a joke)
