Allow for modification of Customer Feedback surveys

[Fasick]

There are times when client misunderstand the survey values and instead of giving the highest value they select the lowest and visa versa.

Once a survey is submitted we can modify the value we can only delete the survey.  Also there are times where perhaps a team members helps someone else and closes out the ticket, but the survey can't be applied to the helpful team member.

The ability to modify an assigned survey result to a differnt team member by an admin or to change the value based on cusotmer discussion is a needed feature.
