XF2 [8WR] XenTorneo 2 (Rankings) PRO 2.3.0.3

• Added a run-down page for all open claims, similar to the unfinalized events run-down page.
• The included importers now use XF2's built-in step-runner system. That means if you have an extremely large forum, you should no longer get memory time-outs when importing large results and matches lists.
  

• Bug fix for people doing straight upgrades from the XF1 version.

• Converted some functions to anonymous functions in order to comply with some deprecation issues stemming from PHP 7.2+
• Fixed some checks for default values when creating new leagues.
• Added differentiated buttons to create primary leagues and sub-leagues.
