Store Only User PB Runs (With Exceptions)

[Gocnak]

Right now we currently store every single run replay on the site. While generous, this is not the final approach we will be taking.

We want to:

• Keep all of the stats and reward cosmetic XP for completion, as the DB entry is far cheaper than the stockpiled replays, and people like their stats (averages)
• On PB, delete the old replay file and replace with new one
  • Only if run was not previously WR. We want to keep all WRs for a "WR history" section on the site so people can watch old WRs
• If not PB, discard replay file (do not write out to file / cloud bucket)
  • I should note that we are using Steam Cloud on the game and will sync everyone's runs they locally have between machines. Steam gives us ~50 GB to deal with for the game, so that should be plenty.
• Keep in mind this is for each category, not the overall map itself. Each person gets 1 PB / category replay saved on the site
