Announcement of left indent, right indent, first line indent / hanging indent in MS word. Based on patch on #1680
Changes since patch:
* Change first line indent into hanging indent in NVDAHelper winword support rather than in speech, and also minus hanging indent from left indent if it exists as MS Word always left indents the hanging indent amount.
* Change the values from floats to meaningful messages (e.g. x characters or x pt) in winword TextInfo's normalizeFormatField rather than inspeech.
* In NVDAHelper winword support code, force collection of fontSize if alignment is requested as paragraph indenting depends on it.
