Ha, well done and shit - I just did the same thing
The new, official version is also up, along with more detailed instructions. You can't imagine how many PMs I answered where people hit Backspace, did it ingame or idontknow...
Maybe we should set up a SVN repository to prevent duplicate implementations in the future? You could also PM me first, so that I know what's happening.
Official changelog:
- v1.4
* implemented UnidHurl => IdHurl conversion found by Kagaamine
* updated in-app instructions since a shipload of people seem to fail hard using this (they might just be unable to read though)
* small refactorings
