Currently our state journal tracks each storage update to a contract, having the ability to revert those changes to the previously set value. For the very first modification however, it behaves a bit wonky. Reverting the update doesn't actually remove the dirty-ness of the slot, rather leaves it as "change this slot to it's original value". This can cause issues down the line with for example write witnesses needing to gather an unneeded proof. This PR modifies the storageChange journal entry to not only track the previous value of a slot, but also whether there was any previous value at all set in the current execution context. In essence, the PR changes the semantic of storageChange so it does not simply track storage changes, rather it tracks dirty storage changes, an important distinction for being able to cleanly revert the journal item.

KYC for masternodes
OVERVIEW
To add a layer of KYC for masternodes in the current system and a sense of ownership amongst the masternodes hence tying such a cluster of masternodes to physical entity which can held accountable for its actions.
Design
We established a bidirectional connection between a candidate and its owner inorder to retrieve a candidate belonging to a specific owner & vice versa.
All the masternodes are recognized by the KYC of their owners and hence are considered as a single verified entity ( for eg. while voting for invalid KYC, only one vote is considered per such cluster )
The contract is very strict in handing out penalty for invalid KYC, it results loss of all funds invested in all of its candidates.
For eg. say A proposes condidates B,C,D by paying for its proposal cost. If at a later stage if some predecided amount of owners ( investors ) vote that a KYC for a A is invalid then A & all of its candidates (B,C,D) will lose their position & all their funds will be lost ( will remain with contract wallet ).
