Coupling project addresses and project distributions

[RonTuretzky]

As suggested by #65 , the current pattern lends itself to mismatch mistakes and administrative errors, is less readable and opens an "evil frontend" opportunity.

• A struct with address and uint256 should be made for submitting the vote itself
• The project distributions can then be a mapping between address and uint256
• Queuing for addition/removal will have to be refactored to accommodate for changes (should simplify implementation)
