Stats Rework (#765)

* Fixed a duplicate check for updates. Changed checking from weekly to daily.

* Refactored how dark variables were accessed to reduce size of component css. Refactored Stats code to use lesser information for reporting.

* Use the installId from the database which is most unlikely to change.

* Fixed a missing interface with stat service

* Added DotnetVersion back into collection

* Updated url to new host.
