Title: Added support for background color in app.rb and solved #41

With this commit, it's now possible to specify a window's background color. The window will default to white if nothing is specified, solving shoes/shoes4#41.
```ruby
Shoes.app :background => :red do
button "hello, world!"
end
```

Those two things still need to be added to the spec.

The file `static/manual-ja.txt` used to have CRLF line terminators. These have been changed to LFs.
