Correcting server errors: clan base attack, maintaining the player's position

Today work was done to correct the flaws on the server side:
- Completely rewritten the logic of maintaining the player's position (you need to test) - the position reset after leaving the game should now not occur the player will appear about the place where the last 30 seconds of the game were;
- Fixed a bug with the capture of bases by clans (reset capture immediately on all bases);
