Move the info about using cloud storage from the FAQ to the Shared
Storage chapter of the documentation. The FAQ entry of the topic is now
reduced to a short answer + a link to the moved documentation.
- Describe how to enable/disable the Shaman in more detail,
- adjust the link to Stack Exchange w.r.t. SAMBA & symlinks, and
- include a table of contents at the top of the page.
Symbolic links on Windows require some special user privilege, and
Shaman can now check for this at startup. Hopefully this helps in guiding
people towards a working Shaman system.
