Fixes #4330
Description of the Change
Fixes MapTool so the save/load is only prevented to/from the actual install directory (and subdirectories).
I have also added a non-editable text field on the Application panel of the preferences dialog to allow users to easily see where MapTool thinks its installed if they need to report errors.
Possible Drawbacks
People could still save/load into the install directories of other versions they have installed, but there is no real way to really determine if a save directory is from another version/install, and we can only protect users from themselves so much.
