32 and 64bit Compatible

Now works on 32 and 64bit versions of MSOffice, the external references did not, without adding a bunch of conditional compilation and basically duplicating the code (once for each platform).
* Changed path '\' references, now added to the end of paths instead of the beginning. Avoids ending up in the "root" filesystem if the path is missing for any reason.
* source\xxx directories are only created if something is going to be exported.
* Added queries in call to SanitizeFiles and skipped yet another apparently useless bit of MS bloat "DOL"
* Removed requirement for all directories to be present in Encoding scripts (batch files).
