Comment 3 for bug 169973

I left the attribute "-inkscape-font-specification" named as is but ensured that it was used consistently as a CSS attribute (fixing the SVG builder code). I went this route rather than an XML attribute based on Richard's guidance. It does seem to make most sense to keep it together with the other CSS attributes because its purpose is to give an alternative description of the same thing (and eventually a description that tells more than the standard CSS attributes). If further discussion is needed on this matter, please let me (and Richard) know.

Added back the font property in SPStyle (an oversight to take it out - must have incorrectly figured new font spec replaced it based on comments about its lack of use in the code). Also made a few small changes as suggested by Richard in the summer. Could do some more major refactoring but to do it well would require touching things I did not work on, which is not safe for this release.
