locationHash doesn't work for albums deeper than 1 level

[EelcoA]

With the current software, the main gallery and the first level albums have working URL's. But when you go deeper, the URL's don't work anymore.

My proposal:
In ProcessLocationHash, inspect the url, check if it goes more than 1 level deep. If it does, load the album thumbnails into the cache, so that the albumID can be found by OpenItem. This can have a performance issue when going very deep into the hierarchy or when albums are very big, but with the current setup this is the easiest solution. It works at my local site now. I had to use jQuery. ajax with async false, because the buildup of the page has to wait until the cache has been loaded.
