Add Contribution contract

Browse Source 
The contribution contract implements an ERC721 interface which
represents any contribution.
The contributions are non-fungible (as opposed to the Kredits tokens)
and can be not be transferred. The contract stores the history of any
contribution.
Contributions can be claimed which will issue the Kredits tokens to the
contributor.

This is an early implementation and misses some access control and
probably more things.
