PATCH: GetFileDialog95A/W (comdlg32)

[Sander van Leeuwen]

Changelog:
- save and restore current directory in GetFileDialog95W if OFN_NOCHANGEDIR flag set
- GetFileDialog95W: only convert ofn->lpTemplateName if it's a string resource id
   (fixes OpenOffice 1.0 file open dialog crash)
- Ignore OFN_FILEMUSTEXIST flag for save file dialog
   (fixes save dialog in ElstarFormular)
- Rewrote casts that some compilers don't accept
