Update to latest patchs

Update:

- Keep Player score
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.
this can be useful, for players not connected enough to rank up or when map is finish too quickly
note: player score is capped to GRLIB_perm_tank

- 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

- Save Manager rewrite
