Further updates to MODS mapping

[sroosa]

All of these need to be ordered correctly within the MODs xml schema: http://www.loc.gov/standards/mods/mods-schemas.html

• [x] add a MODS fields like below for any location values

  <mods:subject>
  <mods:geographic>[insert location name here]</mods:geographic>
  </mods:subject>

• [ ] add a MODS field like below for any contributor and role values

  <mods:name authority='local' type='personal'>
  <mods:role>
    <mods:roleTerm>[insert role here]</mods:roleTerm>
  </mods:role>
  <mods:namePart>[insert contributor name here]</mods:namePart>
  </mods:name>

• [x] add a MODS field like below for any Asset Dates (I think they are mostly created dates)

  <mods:originInfo>
  <mods:dateCreated>[insert date here]</mods:dateCreated>
  </mods:originInfo>

• [x] add a MODS field like below that always has the value News

  <mods:genre>
  News
  </mods:genre>
