[Spambayes] Outlook plugin file locations changing

[Mark Hammond]

For those who don't read the checkins list, I just added the following:

---
Store our config files in the "correct" Windows directory, using the
SHGetFolderPath function to locate it.  If we can't locate this, or can't
create our SpamBayes directory under this, we stick with the "application
directory".

Code also exists to migrate your existing databases to this directory.
First time you run Outlook after this update, your .pck/.db files will be
*moved* to the new directory.  Thus, no re-training should be necessary.

About ready to release a stand-alone SpamBayes Outlook Plugin binary :)
---

If we ever get a platform.py, or decide that there should be a single
database for all spambayes "products" (ie, pop3 and Outlook sharing the same
db, for example), then I will be happy to migrate.

Let me know if you have any problems.

Mark.
