Fix bug in Settings page & GUIDs & missing file

1)
Due to panel managemnt the property tabs were not visible.
Updated and fixed order.
Also visibility flag is updated correct AND size of the window. Panels
now are visible when editing the dialog and not overlapped to avoid
mistakes. Space on the right of main panel is free to move and edit sub
panels.

2)
Also I discovered GUIDs were messed up so I cleaned them and recreated. It's better to avid having duplicate ids.

3)
Application.myapp under web server is missing and SourceSafe is not able to import the project. File appear to be useless. I added an empty (but valid) file.

4) 
added all missing files.

5) 
updated tab order of all modules (Addons directory)
