Operation Log Dialog

Real time operator's actions are broadcasted in the message bar of main windows. However, the bar has limited space, it would be a little difficult for crewmembers to understand sequennce of operations.

Therfore this logging dialog is introduced for the most 20 recent operator's actions including him and other crewmembers. The items are sorted chronologically.

These logs are also recorded in server side in a file so that system manager can retrieve those if necessary. Sometimes, they must be archived to free disk space.
