Change HiveBuzz Level Image retrieval method

Update the way to retrieve users' "level" badge on condenser

Previously one had direct access to an image file. (ex: https://hivebuzz.me/@arcange/level.png)
It's been replaced with an API call (ex: https://hivebuzz.me/api/level/arcange)
If you want to display a "dead fish" when the user has been inactive for more than 30 days, add the ?dead parameter (ex: https://hivebuzz.me/api/level/ned?dead)

API documentation post has been updated accordingly: https://peakd.com/@hivebuzz/api
Image file access will no more work end of this month!
