Milestone Struct Restructuring

[GriffGreen]

This is just to get the conversation going... but this is going to have to change a little bit (Changes in Bold):

struct Milestone {
string name;
string description; // Description of this milestone
string url; // A link to more information (swarm gateway) can be left blank
uint minCompletionDate; // Earliest UNIX time the milestone can be paid
uint maxCompletionDate; // Latest UNIX time the milestone can be paid
address milestoneSupervisor;
// Similar to recipientbut for this milestone
address reviewer; // Can reject the completion of this milestone
uint reviewTime; // How many seconds the reviewer has to review
address paymentSource; // Where the milestone payment is sent from
bytes payData; // Data defining how much ether is sent where
MilestoneStatus status; // Current status of the milestone
// (Completed, AuthorizedForPayment...)
uint doneTime; // UNIX time when the milestone was marked DONE
}
