SAMADCON 0.6.11

Empty attributes in the attribute editor, and preferences split the way GPMC splits them.

Attributes without a value. A tester asked for what RSAT's attribute
editor does: list every attribute an object may have, not only those
that are set. The attribute editor now has a switch, "Leere Attribute
anzeigen" / "Show empty attributes", off by default and remembered by the
browser. With it on, SAMADCON asks the object which attributes it may
have (allowedAttributes) and which of those your account may write
(allowedAttributesEffective), and reads the schema for the rest.

• Empty attributes are listed below the set ones as "not set".
• One can be filled in where your account may write it and it is plain
  text. Constructed attributes (tokenGroups), back links (memberOf),
  system-only attributes (objectGUID), binary values (thumbnailPhoto) and
  attributes SAMADCON edits elsewhere stay read-only; the tooltip says
  why.
• Every attribute now says whether it takes one value or several. For a
  single-valued one the edit dialog accepts one line only, instead of
  leaving the refusal to the DC.

Measured on a Samba 4.22 DC for a user object: 391 attributes allowed,
279 of them writable for the administrator, 38 with a value.

Preferences in two tabs. In GPMC, Preferences ("Einstellungen") has
two branches, and the single tab held types from both. It is now two
tabs, as in GPMC:

• "Windows-Einstellungen" / "Windows Settings": drive maps, registry,
  files, folders, shortcuts, environment.
• "Systemsteuerungseinstellungen" / "Control Panel Settings": printers,
  local users and groups, services, scheduled tasks.
