Improve response time (paginate)

[marcostong17]

Currently movie list is grabbed from FinKino server as xml and it is only possible to get the entire list of schedules for one day or the entire list of movies (no schedules).

Since the phone is able to display a limited number of items on screen, its better to retrieve only few items and then fetch more.

This might not be possible with current architecture, evaluate posibility to use a server like set one in google app engine that fetches the movies and is able to serve requests for pagination.
