/******************************************************************************
* _SHCreateSymbolicLinks [Internal]
*
* Sets up symbol links for various shell folders to point into the users home
* directory. We do an educated guess about what the user would probably want:
* - If there is a 'My Documents' directory in $HOME, the user probably wants
* wine's 'My Documents' to point there. Furthermore, we imply that the user
* is a Windows lover and has no problem with wine creating 'My Pictures',
* 'My Music' and 'My Video' subfolders under '$HOME/My Documents', if those
* do not already exits. We put appropriate symbolic links in place for those,
* too.
* - If there is no 'My Documents' directory in $HOME, we let 'My Documents'
* point directly to $HOME. We assume the user to be a unix hacker who does not
* want wine to create anything anywhere besides the .wine directory. So, if
* there already is a 'My Music' directory in $HOME, we symlink the 'My Music'
* shell folder to it. But if not, we symlink it to $HOME directly. The same
* holds fo 'My Pictures' and 'My Video'.
* - The Desktop shell folder is symlinked to '$HOME/Desktop', if that does
* exists and left alone if not.
* ('My Music',... above in fact means LoadString(IDS_MYMUSIC))
