[WIN32] DLL loading vulnerability

[Elliott Sales de Andrade]

Hi,

This issue seems to be making all the news now.
http://www.h-online.com/security/news/item/Microsoft-warns-of-DLL-vulnerability-in-applications-1064584.html

Since it exploits the default current-directory-in-DLL-search-path, I
would assume the only possible problem is through the protocol
handlers as I'd think Pidgin would normally have a sane current
directory set otherwise.

But we've had issues with aspell.dll in the PATH before, and I noticed
Daniel made some changes to our LoadLibrary calls that might be
related, so I'm bringing it up now to see if there's any need to make
a release or something.
