- Randomize denoms calculated ot of vecAmounts. Should help to find partners faster/more often and maybe slightly improve anonymity also.

- sessionTotal doesn't makes sense anymore, get rid of it.
- GetDenominationsByAmount cleaned but it is not used anywhere else so maybe it should be removed too (placed a comment there but didn't remove it yet).
