enables to install fonts via cookbook files

Adding font provider for installation of fonts via cookbook files.
Simply add the font into your cookbook files, depend on the windows cookbook and target the windows_font "your_font.ttf" within your recipe.

You just create another cookbook and drop the fonts in the files/default folder.
Then depend on the windows cookbook and use the provider to install them.
Example within the recipe:

```
%w(apl385.ttf
   BodonBEBol.ttf
   BodonBEIta.ttf
   BodonBEReg.ttf
   dyalogal.fon
   dyalogaltk.ttf
   dyalogal.ttf
   QUADBD_.ttf
   QUADI__.ttf
   QUAD___.ttf
   QuaSBd_.ttf
   QuaSIt_.ttf
   QuaSRg_.ttf).each do |f|

  windows_font f do
    file f
  end
end
```

That will copy the files into the right location and (because it's using wscript to copy) registers the fonts as you would do by copy them via explorer. Really could not find a better way. Tried to use the native C calls by importing the ffi api hooks, but it seems to do something nasty in the background. If you want to chat about this, please call me on skype: sander.botman@gmail.com.
