Changing Bomb Reward to Per Person instead of a pool

[MrPeanut1028]

Some smaller bombs (11 modules) can give insanely high rewards if a small numbers of players participate, and this only gets worse as bombs get bigger. We removed mission bomb rewards for this reason. We could probably add them back if the system changed to player-based. It could be something like (0.2 x modules) + (0.1 x anything from BR on score sheet). These values (0.2 and 0.1) could probably be made settings so they could be changed on the fly / locally if necessary.
