BTimes Map Checkpoints are not intiutive

[EliotVU]

It is not clear how a player can disable a map checkpoint once it is set.
A solution to this would be to disable the checkpoint as soon as the player dies by a "suicide", a checkpoint should only remain active if its instigator death was due the environment.

The only downside to this is the fact that deaths caused by crushing movers are recognized as a "suicide".
