Fix for issue 3709 (control-panel: value of "Backup Path" field should be the instance path and not the installation path in the Backup/Restore panels)
The code has been update to use the instance path instead of the install path in different places (the default backup directory, the path to be used to retrieve the java properties file, etc.).
If we are dealing with a package installation (install and instance paths are different), the control panel and the status command-line will display two paths: one for the install and the other for the instance.
