Subject: [PATCH] tdf#102261: introduce editeng paragraph tab stop default
 distance

Adds mnDefaultDistance to SvxTabStopItem that if defined
will set a paragraph wide tab stop default distance and
override the document wide setting.

Also makes editeng consider mnDefaultDistance while getting
tab stop default distance.
