tdf#150408: Implement "Legal" numbering (all levels using Arabic numbers)

Enabling this feature on a list level makes all numbered sublevels, that
constitute the number of this level, to use Arabic numerals. This doesn't
change the labels of other levels: e.g., if level 1 uses A,B,C; level 2
uses i,ii,iii; level 3 uses a,b,c, and is "Legal"; and level 4 uses 1,2,3;
then a list may look like

A. Something
A.i. Some subitem
A.ii. Another subitem
1.2.1. This is a "Legal" sub-subitem
A.ii.a.1. And its child

This improves interoperability with Word.

This change introduces document model, ODF and OOXML import and export.
In ODF, a new boolean attribute of 'text:outline-level-style' element,
'loext:is-legal', is introduced; its default value is "false".
