Better round end tracking

[ChillerDragon]

Check sv_scorelimit on round start to early track wins and looses not only for 1000.

to fix the bug:

sv_scorelimit 1000 is strongly recommended if scorelimit is lower the wins and looses will be calculated on new round start. So all players who leave during end screen won't be tracked. If the scorelimit is 1000 the wins and looses will be saved instantly on the 10th capture.
