pptx: Line up continuation paragraphs

This commit changes the `marL` and `indent` values used for plain
paragraphs and numbered lists, and changes the spacing defined in the
reference doc master for bulleted lists.

For paragraphs, there is now a left-indent taken from the `otherStyle`
in the master. For numbered lists, the number is positioned where the
text would be if this were a plain paragraph, and the text is indented
to the next level. This means that continuation paragraphs line up
nicely with numbered lists.

It also /mostly/ matches the observed PowerPoint behaviour when
inserting paragraphs and numbered lists: the only difference is that
PowerPoint was using a different margin value for the first level
numbered lists – I’ve changed this to match the other levels, as I don’t
think it makes the spacing unappealing and it allows continuation
paragraphs at any level to line up.

With bulleted lists, I’m keeping the observed PowerPoint behaviour of
specifying only a level, letting `marL` and `indent` be automatically
taken from `bodyStyle`. To that end, this commit changes the `bodyStyle`
spacing in the master of the default reference doc, to:

- line up the text of the first paragraph in each bullet with any
  continuation paragraphs
- line up nested bullet markers in any continuation paragraphs with the
  first paragraph, matching lists and plain paragraphs

This does mean the continuation paragraphs still won’t line up for
anyone using their own reference doc where they haven’t matched the
`otherStyle` and `bodyStyle` indent levels, but I think people in that
situation will be able to troubleshoot.
