Hotfix/1.4.2.3

[Zukunftsmusik]

• Fixes CSV output of fleet data:
  • Changed delimiter from tab (\t) to semicolon (;)
  • Any fleet or player name enclosed in double quotes is escaped so that upon importing the data in excel, it'll still be enclosed in double quotes
  • Any fleet or player name containing the delimiter is now escaped in double quotes
  • Any fleet or player name containing a number is now escaped in double quotes
