Targets could have different scores

[jspjut]

This is a feature request to allow targets to have different scores that get added when the target gets destroyed. If we want to go above and beyond, we could even allow for independent scoring on hits, and even miss scoring. Here's a quick idea of which experiment parameters to consider adding:

• missScore: default to 0 and a part of the general config
• targetHitScore: default to 0 and a part of the target config
• targetDestroyScore: default to 1 and a part of the target config
