Lakewalker error

[avar]

Lakewalker keeps re-downloading already downloaded IR1 images on current JOSM:

java.io.FileNotFoundException: /home/avar/.josm/plugins/Lakewalker/IR1/landsat_4000_2000_xy_-84000_260000.png (No such file or directory)

This can be fixed by doing mkdir -p /home/avar/.josm/plugins/Lakewalker/IR1/, but the plugin should check if its cache directory exists and create it if it doesn't.

I have a fix already. Let me test it a bit before submitting...

[osm@…]

patch enabling cache. Also prepare for cleanup, ref 1808
