Fix a number of issues with David's approval:

1. A char array was set to NULL wrongly which caused a core in the windows services code.  This problem appeared almost systematically when the install path was long.
2. The windows services code got into an infinite loop when the server could not be started.
3. The windows services code was missing to unlock a file after testing if it could lock it.
4. Create specific loggers for Setup, Uninstall and StatusPanel applications.  This avoids having duplicated and not very user friendly log lines on the output of these applications.
5. When we cannot launch the graphical applications store the stack trace we get in the log file associated with the application and inform the user about the existence of this file in the same message where we tell that we are falling back to the CLI mode.
6. Fix a refresh problem in the status panel.  Now when the number of entries of the database increase the contents of the panel are automatically updated.
7. Modify the name of the Age of Oldest Missing Changes as mentioned by Brian.
8. Redirect some logging/debugging lines of the windows services to a file called windows-service in the logs directory.
