This commit adds it to the three places where paragraph formatting can
be applied right now (directly on the paragraph, paragraph styles, and
bullets/numbering styles). I'm separately adding an entry to the wiki
regarding what these methods do (widow/orphan control)
In MS Word 2015 (and possibly others), leading and trailing spaces are
ignored in text runs. This means that calling TextRun with
leading/trailing space would result in a document that didn't include
those spaces. The fix here (per http://officeopenxml.com/WPtext.php)
is to include an extra attribute on the "w:t" element that forces word
to recognize those spaces.
Instead of forcing table cells to only have a single paragraph as
their content, we now check whether they end in a paragraph (and
insert one if necessary) during #prepForXml
These errors only arose because I didn't run `npm build`, only `npm
test`. Then, when I tried building the null checks failed. Keeping the
two config fiels in sync will help prevent this issue in the future
This change brings increased type safety to uses of
XmlAttributeComponent. Now the compiler is checkign for us that the
properties that get passed in to every subclass match the intended
interface, and also that the xmlKeys property -> xml attribute mapping
has all the right keys
I checked the spec, and "w:pPr" does not take any attributes. I also
converted the paragraph tests to use the deep.equal style to get rid
of some more jsonify!
