Cleanup Various PR & bring some of the NO6 private branch changes into main

[jt-traub]

• Update rules for FACTION command (Fix for text describing the FACTION command, in the presence of MARTIAL #157)
  • Fix for text describing the FACTION command, so that it works for the case of martial factions as well.
  • Rules snapshots updated in later commit (bd0758f)
• Add the map cities map output that @artyomtrityak put on the private NO6 branch (no PR)
  • This allows dumping all the surface city names to post for the cities win condition.
• Allow the orders checker to check faction password.
  • Will report an error if the orders are submitted with the wrong password. (Orders checker checks that password is valid. #133)
  • Unit tests added in later commit (bd0758f)
• Remove freezing code and add counting of winner (the winning count was part of Updated Makefile to avoid recursive make #131)
  • Freezing changes were only relevant for NO6.
  • Cleaned up the winning count and made it enablable by a change to extra.cpp in neworigins.
    • Not done as a global since win conditions are very game specific.
• Another couple of small changes from the above PRs
  • Report and event for practice (Updated Makefile to avoid recursive make #131)
  • Report what item wasn't valid for transport in a transport order (Orders checker checks that password is valid. #133)
  • Snapshots for games updated to reflect the practice change in later commit (bd0758f)
