Option to reload currently visible tiles

[GoogleCodeExporter]

This is an enhancement patch.

What steps will reproduce the problem?
1. View the map using OSMDroid
2. The viewed tiles are now in your cache on the sdcard
3. Update the map with JOSM or potlatch
4. You still see the old, obsolete tiles

What is the expected output? What do you see instead?
There should be an option to reload the currently visible tiles, as suggested 
in issue 40 and issue 44.

What version of the product are you using? On what operating system?
Current svn (r454), android 2.1

Please provide any additional information below.
This patch provides a new method OpenStreetMapView.removeCachedVisibleTiles , 
and a menu option in the OpenStreetMapViewer sample to call that method.

The method calls cache and filesystem methods to remove the tiles in a given 
rectangle at several zoom levels.

Please review and let me know what you think.

Many thanks,
-Jeremy Monin

This can be achieved with:

mMapView.getTileProvider().clearTileCache();
