Incorrect path to geotiles in atlaspr.js

At first, I was unable to get this to work. After some tinkering i noticed that it's looking for the geotiles directory in .. instead of .
The instructions tell you to copy the geotiles directory on the same level as the js directory, and i think the instructions are correct.
I went to line 8 of atlaspr.js and changed ".." to "." and now it works like a charm.
