Improve Lists in few areas

[PrzemyslawKlys]

Initially, when you add more than one list of the same style, it seems it's continuing numbering. While it's "ok" it's not as it was designed. When you use AddList(), it's supposed to create a new list and start from 1. It's not doing that now.

This PR:

• forces every new list to start from "1", instead of continuing
• adds the ability to choose that you want to continue numbering

This is initial commit, that seems to work using

LevelOverride levelOverride1 = new LevelOverride() { LevelIndex = 0 };
StartOverrideNumberingValue startOverrideNumberingValue1 = new StartOverrideNumberingValue() { Val = 1 };

But it seems that what Word sometimes uses is Nsid

Nsid nsid1 = new Nsid() { Val = "21351BF1" };

Why Word chooses one over the other - I've no clue.

• adds ability to add lists to Headers and Footers
• adds ability to add lists to TableCell (notice how paragraphs are handled in code)
