[arch-haskell] add haskell-yaml and haskell-svgcairo

Hello, Could the yaml [1] and svgcairo [2] packages be added to [haskell]? I don't have a particularly good reason why except that I use both packages in some of my pet projects. [1] http://hackage.haskell.org/package/yaml/ [2] http://hackage.haskell.org/package/svgcairo/ Thanks, Linus
