Add NT quota support. Patch from Stefan (metze) Metzemacher

1. Allows to change quota settings for shared mount points from Win2K and WinXP from Explorer properties tab
2. Disabled by default and when requested, will be probed and enabled only on Linux where it works
3. Was tested for approx. two weeks now on Linux by two independent QA teams, have not found any bugs so far
