[Xastir] Script to cache some maps

[Andrew Errington]

Surely the ultimate solution is to download vector data and have a
well-written dbfawk which shows the elements you are most interested in?

Vector data takes up much less space than tiles, and setting up a tile
server is not actually straightforward (plus, you have to download the
vector data to make your own tiles anyway).

I run OSMAnd on my phone.  It uses vector data and renders it on the fly,
so all my mapping (and routing) for the whole country is done locally (no
network needed).
