Fixes two issues with ingesting a .docx file. First, a tab exists as a child of a tabs element, not an r element (fix in HelperFunctions.cs at line 146). Second, an rFonts element may not have a cs attribute, but instead may have an ascii, eastAsia or hAnsi attribute (fix in Formatting.cs at line 101).
