* FontFamily::GetStyle() now looks for alternative names when a specific

style couldn't be found, ie. when looking for "Roman", "Regular", and
  "Book" are accepted, too, and "Italic"/"Oblique" are now synonyms as 
  well.
* This prevents StyledEdit from using the "Condensed" style when it does 
  not find a certain font.
* Minor cleanup.
