* Refactored Stats code to be much cleaner and user better naming.
* Cleaned up the actual http code to use Flurl and to return if the upload was successful or not so we can delete the file where appropriate.
* More refactoring for the stats code to clean it up and keep it consistent with our standards.
* Removed a confusing log statement
* Added support for old api key header from original stat server
* Use the correct endpoint, not the new one.
* Code smell
* Fixed opds url display
* Rewrote how stat collection works, now we check in multiple places and always run stat collection in a background thread, to not block main thread.
* Cleaned up the ParseInfoTest to be more verbose
* Added benchmarking
* Cleaned up error interceptor to avoid sending auth errors (when a 500 occurs) to sentry as auth errors aren't issues.
* Added extra stat collection
* Fixed a bad gitignore which ignored anything in a stats directory
