Improved tracking code over HTTPS & obfuscated from crawlers

- Force HTTPS to help reduce interference in transport
- Obfuscate the URL to help reduce the effect of crawlers (hopefully)
Massive refactor of stats & hide public data for sites

- No longer show specific numbers for other sites, simply show averages
- Refactor the stats javascript code to be more manageable
- Updated tests and using SSL now for the tracking code
