Problem: When all Javascript macros and libraries are removed from a document,
an empty directory "Scripts/javascript" is left over in the document file. When
the document is re-opened, the user will be presented with the Enable Macros or
Disable Macros question, even though there are not actually any macros in the
file anymore.

I am using Gentoo Linux, but I think this applies to any platform. This issue
occurs in every OOo program that has Javascript macros, and it doesn't matter
whether the file is saved as OpenDocument or as OOo 1.0 format.

Steps to reproduce:
1. create a new document or spreadsheet;
2. create a javascript macro library (and a javascript macro if you like) in the
current document;
3. save and re-open your document;
4. remove all javascript macros and javascript libraries from the current document;
5. save and re-open your document;
6. you'll see a warning asking you to either Enable or Disable Macros.

Expected result: The Scripts/javascript directory should be removed, so that the
warning/question described above is not shown.
