Pool / Incentivized Pool Interface update

[snake-poison]

Hm.. since we will only go with one pool for now it is okay. It might however be helpful if we have multiple pools but until then we already might have everything on-chain.

This just prompted me to think about how we plan on incentivizing pools by different amounts which wouldn't be , that will need to be included here. So I think you are onto something here with a pool type or at least an incentive weight.
