STYLEREF fields show each page's result in headers and footers (#775) (#882)

* #775: STYLEREF fields in headers and footers show each page's result

Running headers/footers with STYLEREF (e.g. the current chapter title) are
evaluated per page at layout time (ECMA-376 §17.16.5.59): the page's first
paragraph of the style (\l: last), else the nearest before, else after.
Style names/ids, heading levels (STYLEREF 1), character styles, and the
\n \r \w \s \t \p switches. Body STYLEREF fields update with the other
fields. STYLEREF added to Insert › Quick Parts › Field with its options.

* #775: STYLEREF error text in our own words

* Review fixes for #882: translate the STYLEREF Field dialog strings

Adds the style picker label, the six STYLEREF switch labels and the
STYLEREF description to all 18 interface catalogs.

* STYLEREF: reuse the style index while the body and styles are unchanged

Headers with STYLEREF rebuilt and hashed the body's style index on every
layout pass (echelon's follow-up note on #882). The layout cache now keeps
the index with the body blocks it came from (shared, so an edited block is
a different pointer) and the styles/numbering hash, and rebuilds it only
when either changed.

A document only "opens correctly" if its pages break where Word breaks them: the same lines, the
same page count, footnotes and pictures on the same pages. This checklist covers line breaking,
