Increase efficiency by reducing to use Only 1 file for repeat tiles.

[GoogleCodeExporter]

What steps will reproduce the problem?
- Specifically if you look at the ocean tiles, THEY ARE ALL THE SAME. In fact 
they encompass MOST of the tiles downloaded. They look the same, and file size 
is also, exactly the same. 

>>> Instead of downloading the same files millions of times, and even worse, 
saving it a million of times under different file names, set master tile and 
skip download/save of similar tiles.

Please provide any additional information below.
- Other tiles which are identical could be found under unpopulated lands where 
the terrain is the same such as is widely available in google's default map 
style.

- This is less prominent in satellite-imagery maps, though still exists.

- I attached an example of the most replicated file in folder-base for tiles.

I see your point, but...

You probably are doing mass-downloads of the entire world for google map, 
Google is not too happy about the, read Issue 210.

My recommendation: download only what you need (not form google), if what you 
need is a lot you should use download.py create a script or batch that gets 
what you need.
