Bug Description
Would be nice if the user can download all the tiles for a given area ahead of time and over a cheap connection.

This feature is VERY important if you don't have a data plan. There is already one method to do this: you can load map tiles directly onto the SD card as noted in Issue #64 (and probably elsewhere).
The attached patch adds another solution. The patch adds a menu option that will take the current route and animate along it.
This is useful in two ways:
* It allows you a brief overview of where you're going.
* It primes the cache with all the map tiles along the way.
On the first animation, I often don't see much - I see an animated display with lots of 'loading...' squares. This is actually by design - I don't wait until the tiles are loaded before continuing the animation. The tiles needed get added to a queue and will all be downloaded in turn.
I didn't want to completely overload the OSM tile server, so there is no way to download the tiles in a region, only along a planned route. Also, only the tiles for one zoom level are downloaded (although you could zoom in/out and repeat).
