Bug Timers are cumulated on MP server list (memory leak?)

1) Start the game,
2) Go on multiplayer screen,
3) Check that the timers on each server are counting 1 second per second,
4) Go back to main menu,
5) Go again on MP screen,
6) Check that timers are now counting 2 seconds per second,
7) Repeat N times points 4) and 5),
8) Check that timers are counting 1 more second per second for each time you displayed the MP screen.

Although this is graphically a minor bug, this kind of bug is often related with a memory leak. And memory leaks are often related with later major issues. ^^
