Optimization speed ups using initpeople and absolute constraints

[kelvinburke]

This is ready to merge without problems (I hope) but should address this question first Further Questions: Multioptimize should run with nblocks now? How many blockiters, chains and blocks should we have?

Things to do yet: Make ICERs and BOCs use absconstraints and initpeople

Scenarios tab load time still not finished

All ready I believe
