Hi,
This is continuation from #4056:
After testing 4056 bug fix, I found that this affects other Office programs such as Word and Excel. Specifically, the issue and the workaround is as follows:
In MS Office 2010 (at least), combo box names in options dialogs are not announced by NVDA - only values are spoken. This would be because the text of the actual combo box name is an object by itself, located to the left of the combo box; thus, the obj.name is the previous sibling of the combo box.
As it affects Office programs such as Outlook and Word, a general workaround was implemented as follows:

• Added an overlay class in NVDAObjects/UIA named MSOfficeComboBox.
• The job of this overlay object is to fetch the real name of the combo box, which would be obj.previous.name. However, in UIA.UIA, we cannot use variables such as name directly, thus used _get_name and _get_previous.
• Once we locate the previous object, fetch its name and return this string in overlay._get_name.
  For commits and try build, see ticket Office 2010 with UIA: Name for combo boxes in Options dialog are not announced #4056. Thanks.
