- Remove _SHExpandEnvironmentStrings and replace calls to it by usual ExpandEnvironmentStringsW calls.
That function didn't really do what it should as it replaced some variables by faulty generated values instead of their actual values. Fixing this gets us rid of our duplicated "Administrator" directory, so the only remaining Admin dir is "Administrator.REACTOS" created by userenv. This might also fix the SHGetFolderPathW timing issue, which was hit by rosautotest from time to time. - In turn, removing that function makes it possible to get rid of the now unused _SHOpenProfilesKey and _SHGetProfilesValue functions. svn path=/trunk/; revision=40439
