Added new Para Styles

[Nj221102]

Description

Added some more para styles like font-variant, font
updated some para styles like font-family, emphasis

emphasis wasn't working before because it wasn't mentioned in shoes styles in lacci/lib/shoes/drawables/para.rb
font-family was mentioned as font in shoes styles so i changed it to family .

Shoes.app do
    
    para "this text is in normal styl" , emphasis:"italic"

    para "this text is in italic style" , font: "italic normal bold 16px/1.5 'Times New Roman', serif;"

    para "this text is in oblique style " , family: "'Pacifico', cursive;"

end

Shoes.app do

    para "This is Normal Variant" ,font_variant: "normal"


    para "This is Small Caps Variant " ,font_variant: "small-caps"

  end

Mostly this is really good. But it does seem to break the existing font functionality. Example:

Shoes.app do
  para "Text in Helvetica", font: "Helvetica"

  para "And in Lucida", font: "Lucida"

  para "From an example", :font => "Trebuchet 20px bold"
end

I think we're going to need some kind of parsing of the "font" property in Lacci for this.
