Justin Luth 0d3748e5fb tdf#163598 editeng: avoid using fake outline depth
Most implementations do not actually
do anything meaningful with Get/SetDepth,
so don't exception or accept their values.

To fix the bug, I could have just checked for
dynamic_cast<SvxEditEngineForwarder*>
(since it supports EE_PARA_OUTLLEVEL directly)
but this way seemed more encompassing.

The potential downside is that EE_PARA_OUTLLEVEL
will be requested as a real property
after GetPropertyValueHelper
with some of these dummy providers,
and who knows what UNO might do about that...

IF this patch causes problems,
then I need to implement Get/SetDepth
in SvxEditEngineForwarder
(or consider the dummy providers as SupportsOutlineDepth).
