Update to latest patchs

Update:

now, players score and permissions can be restored when the map is finish or when the wipe savegame is asked, if "Keep Players Datas" server parameter is enabled.

- Load / Save game
add to the admin menu the load/save game feature
you can manually load the current game state, (in clipboard), and backup it to a file.
and later, paste the backup file and save it in LRX
note: all players will be disconnected when you use save game

- Squad backup
now, the player and his squad are saved on disconnect (including loadout!)
they reappear when the player get back
