Patch for M3 bug #2226. [PATCH] File->Open dialog does not 'remember' browsing directory. The patch fixes WIN32. It also defines member variables and functions for Mac and Unix to keep tinderbox building. Mac and Unix need implementations which honor the SetDisplayDirectory method so that the browsing directory is actually set.
