Favicon to MurmurHash wót Maltemo

Detects the number of favicon in the current page and update extension badge consequently.
Every hashes are listed in the menu, you can click on them to get directly to the related shodan search.
You can also copy the url of the favicon.
When you open the extension menu, the following actions are made:
- Searches for every favicon in the page
- Tries to download them (CORS policy might block the download unfortunately)
- Transform them in base64 then in murmurhash (same process as Shodan).

No analytics. No data sent to third parties. No bullsh*t.
