support for line breaks like <br> tag

[satyajitnayk]

• The equivalent of force line break using <br> is <w:br/> in DOCX XML openofficexml.

• Linebreak for paragraph is working fine.

[satyajitnayk]

As of now the library converts <br> to

<w:pPr>
  <w:spacing w:lineRule="auto" />
</w:pPr>
<w:r>
  <w:rPr />
</w:r>

1. which is correct for line breaking a paragraph ,but doesn't seems right for force line break.
2. For example: converting "hello I am sam \some bold\ \
   \
   some other texts" to DOCX XML is not working , as linebreak under same text run , rather than different paragraphs/text runs.
3. Instead <w:br/> is correct conversion as per documentation of openofficexml.

After conversion to docx, in < br/> It will be followed by a blank line
