Improvements on the Obstacle game mode

- Fast respawn setting (S_FastRespawn). Allow players to respawn instantly on the latest activated checkpoint. This create a bug on old maps that use a pole block as a checkpoint. If a player try to fast respawn on this checkpoint the script will crash and restart. To fix the problem you just have to open the map in the editor and save it with the latest version of the title pack. Alternatively you can disable the fast respawn on old maps by setting S_FastRespawnOldMap to False in your MatchSettings file. Only a few maps use pole as checkpoint, so the fast respawn is enable on old maps by default.
- Jump to checkpoint setting (S_AllowJump). Press alt and display the checkpoints best times scores table. Click on the checkpoint number button and you will be teleported to that checkpoint. Your time will be invalidated and you won't be able to activate the final goal.
- Respawn penalty setting (S_RespawnPenalty). Give a time penalty to players who respawn at a checkpoint.
- Display the ranking of the player above his time at the checkpoint when he activates it.
- Use a Storm styled background for the scores table.
- Bump version number. Mode : 2.4 (2014-07-15) -> 2.5 (2014-12-18), MapType : 3.4 (2014-07-15) -> 3.5 (2014-12-18)
- Fix deprecated variables on CSmPlayer.
