Bug/Issue: Site-Data unable to be cached

[CasuallyCorporate]

Site data cannot be cached as it is only requested via it's id. This is not unique across game variants.

ToDo:

• [x] Add game variant to site info requests
• [x] Handle game variant per request for site info
• [x] Trace through to ensure correct functionality

• [x] Changing reload on null behaviour to remove endless loading animation on failure.
