Improve LogosNestedHyperlinkPostprocessor

Turns out that when the document contains complex scripts, text ranges
in the Word document may get split across same formatting. The
LogosNestedHyperlinkPostprocessor depends on same formatting being in
only one region (for the hyperlink regions). Therefore, search for such
regions and merge them (showing a warning) before converting.

This should fix issues with Burmese bibles.
