Winfileassoc.cpp
Handles file associations in Windows 7/Vista/XP/2000.
We assume that the code is run without administrator privileges, so the associations are done for current user only.
System-wide associations require writing to HKEY_CLASSES_ROOT and we don't want to get our hands dirty with that.
Each user on the computer can configure his own set of file associations for SMPlayer, which is extremely cool.
Optionally, during uninstall, it would be a good idea to call RestoreFileAssociations for all media types so
that we can clean up the registry and restore the old associations for current user.
Vista:
The code can only register the app as default program for selected extensions and check if it is the default.
It cannot restore 'old' default application, since this doesn't seem to be possible with the current Vista API.
Add libole32.a library if compiling with MinGW. In smplayer.pro, under 'win32 {': LIBS += libole32
Tested on: WinXP, Vista, Win7.
