[DISCONTINUED] GitHub Release Download Counter per Mat Muller

Attention: Due to recent changes in GitHub's web layout & API and my lack of spare time to support this extension, I decided to drop support for this addon.

This extension will display the download count of release assets from public GitHub repositories next to the asset size.

Notes:

* Due to GitHub's API rate limit the maximum number of unauthenticated API requests is of 60 per hour. This means that this extension can only show the download count of assets of up to 60 releases per hour.
* This app is intended to be used by small developers who want to see how many times their releases have been downloaded.
