Track crowd similarity source + interactions

[ArielMant0]

The server should serve priorities for games. In addition, the crowd-sourced similarity data should include

• where the similarity came from
  • game
  • crowd
  • name
  • search
• number of people who submitted similarity (for each source??)
• similarity value (for each source??)
• crowd id for existing user accounts
• excluded games per user account (local storage)

Features to consider for security reasons

• number of submissions per id (prevent bots?)
