v2.1.5

• Auto-updating versions.txt from Nut TitleDB, also (so now version info comes from Bob's and Nut's DBs)
• Only downloading Nut TitleDB files when there was a new commit
• Added NUT_TITLEDB_LANG_FILTER option to only download language+region files that include a string you set (leave it blank to get them all)
  So if you only want to to update US titles, set NUT_TITLEDB_LANG_FILTER to "US".
• Updated nut to ad853c8ba773f2814317c570321b4e4ee6683393 (before scrape feature was removed)
