v6.4.3

Maintenance release

• fixing a rare bug, when "after_set_conditions" event isn't called in Master League
  (which led to subtle errors in such modules as StadiumServer and ScoreboardServer)
  thanks to Sickbeard who reported it.
• documentation updated: added previously missing info on:
  "set_home_team_for_kits" and "set_away_team_for_kits" events

v6.4.2

A few small updates:

• "ctx.kits" updates: new "SleeveLimits" kit attribute and corrections for number
  positioning on the shorts (new range for "ShortsNumberX" and "ShortsNumberY": 0-31)
  Thanks, zlac and Hawke!
• new scripting lib: "fs", with function "find_files" for listing/searching directories
• audio lib update: new function "get_state" for sound objects
