Add TimeSent field to ExecutedAction for more detail

Created by: f1rehaz4rd

This PR adds the TimeSent field into the ExecutedAction data structure. The purpose of this is to allow for the teamserver to know how long ago that it sent the action out. With this field you will be able to tell as an operator if a command was sent out and never got back. Also, the operator will know if there was an unusually large delay in the response as well.
