Support for footnote.

A footnote is two thing :

• in the document.xml, at the place of the referecence :

<w:r>
  <w:rPr>
    <w:rStyle w:val="FootnoteReference"/>
  </w:rPr>
  <w:footnoteReference w:id="1"/>
</w:r>

• in the footnote.xml the content of the footnote :

<w:footnote w:id="1">
  <w:p w:rsidRDefault="00D935D7" w:rsidR="00D935D7">
    <w:pPr>
      <w:pStyle w:val="FootnoteText"/>
    </w:pPr>
    <w:r>
      <w:rPr>
        <w:rStyle w:val="FootnoteReference"/>
      </w:rPr>
      <w:footnoteRef/>
    </w:r>
    <w:r>
      <w:t xml:space="preserve"> Note</w:t>
    </w:r>
  </w:p>
</w:footnote>

@scanny Hey, I’ve started working with python-docx, and i’ts great. I’ve been looking for ways to add FootNotes, and have seen the problem I’m facing is not new reading this issue.

1. Possible to merge the Read-Only-Footnotes functionality added by ludoo? (at https://github.com/python-openxml/python-docx/pull/53#issuecomment-453834065)
2. Adding the Write-Footnotes functionality as Huyston requested? ( at https://github.com/python-openxml/python-docx/issues/1#issuecomment-73216969)
3. Can either you @scanny or @ludoo help me figure out how to add new FootNotes to a new/existing docx file? The API usage will be best, something like “run.add_footenote(‘Footnote text’)”, but can’t, well, is there any other way to do it programmatically other than opening up the xml-file after it as been compiled as docx, and adding hardcoded-string to that file? An Example of usage will be very appreciated. Thanks so much.
