OK, so how to do this? I see 3 ways:

1. Implement an extra api that do the same as the normal file open/save 
and browse for folder api, but then with the Unix file system
2. Implement a thread local variable so that threads can put the Wine 
file dialogs into unix file system mode / windows file system mode
3. Define some magic wine flags in the file dialogs that make the 
dialogs appear in Unix mode

There are some pro's and con's to all of them:

1. Well, basically, we have to make an extra api :-), so there are more 
functions exported. Probably the existing and new functions will need to 
call each other, so this means an extra level of indirection.
2. Kinda ugly hacking, though we don't loose win32 compatibility
3. Nice, but we loose strict win32 compatibility, since there will be a 
magic flags that doesn't exist in win32.
