Currently only the FilterType can be set. If value is set to false it's
ignored - devicedata is not touched in this case.  Other options could
be added this way later.

There is no explicit getter, as this value is available in
GetDeviceDetails() or ListDevices(). If it's not there, then it's not
set = unlimited.

Code can be extended to support a different filtertype per folder (e.g.
for shared folders). Still, only the FilterType MAX from the config is
supported (user can not superseed server value).
