Updated to 1.5 and moved to SVN for hosting and updates.
JickenWings appears to be updating although their latest news suggests otherwise. The ranking of complete collections is not, however, updating so the script will report "does not seem to ranked" until that changes.

In order to keep the cache file up to date (and detect when items are no longer in the DC) there is now a cache cleaning step that deletes data from the cache if the cache count and the DC count are different. At the end the script now searches for items in the DC that do not have a cache entry and creates one. This last step is throttled so that JickenWings does not get hammered. These items are generally items where there is exactly one in the DC, one is enough to rank but the rank has not been updated within the time window.
