... in WhichRangesContainer and SfxItemSet ctors. Now it's not needed
to explicitly use 'value' in WhichRangesContainer's ctor, or create an
instance for use in SfxItemSet ctor (svl::Items is already defined as
a template value of corresponding type).
Instead of
WhichRangesContainer Foo(svl::Items<1, 2>::value);
SfxItemSet Bar(rItemPool, svl::Items<1, 2>{});
now use:
WhichRangesContainer Foo(svl::Items<1, 2>);
SfxItemSet Bar(rItemPool, svl::Items<1, 2>);
