* Add kernel commitments sum and kernel and output MMR sizes to block header * Sum a block without including previous sums, cleanup. Blocks are now summed and validated based on their own totals and not the totals since genesis. This allows to get rid of BlockSum and simplified the setting of a new block's roots, kernel sum and MMR sizes. Fixes #116 * Additional kernel MMR validation to check all prior header roots successively * Wallet tests fix
