patch

In poppler/GlobalParams.cc, winFontList is set to NULL in the constructor within a #ifdef WIN32. It is not changed anywhere (that code was removed in 9ced4442372d08375e0ded62f79052d8a3ec9cd6) and then an attempt is made to delete it in the destructor, which is a delete of NULL pointer (which could be a possible crash/security issue).

The attached patch fixes this issue and removes the WinFontList and WinFontInfo classes which aren't used anywhere in the code.
