Subject: Applying Gail's patch for font-specification (Closes LP: #169973)

- New attribute in an object's style string called
-inkscape-font-specification stores full font name

- This will be useful when we can support fonts that don't fit into the
confines of CSS (if either pango enhances their PangoFontDescription
structure, or we can get around its limitations)

- Framework in place to separate font families from their "styles"
  (faces)
in the text and font dialog - need only the code that does the actual
separation

- Text and Styles dialog shows only fonts it can handle
