This reverts commit eb667fca9f31b28888d877f84c40dfcea5eec962.
Fixed a bug for TextBlock. Try out the following snippet.

Shoes.app do
  msg = para 'shoes', stroke: red
  button 'replace' do
    msg.text = 'hello hello'
    gui.flush
  end
end
Implemented Image#path.

* refer to #252
* fixes #252
* i'm not certain how to write tests for this, but i'm certain it needs some
Ported textcursor from Purple Shoes. Try out the following:

Shoes.app do
  msg = para 'hello ' * 20
  msg.cursor = -1
  keypress do |k|
    n = case k
      when 'ARROW_LEFT'; -1
      when 'ARROW_RIGHT'; 1
      else
        next
    end
    n += msg.cursor
    len = msg.text.length
    n = len unless n > -1
    msg.cursor = n % (len+1)
    gui.flush
  end
end
simple image path test
Merge pull request #277 from hkal/implementing_image_path

Implemented Image#path.
Removed sample31 from the list of working samples for now

* not working on Linux and Mac
* please reference #276
* [skip ci]
Cleaned up the bin directory of swt-shoooes stuff

* now there are only 3 executables: shoes, shoes.bat and ruby-shoes
* done to avoid confusion as to which executable to use
* Adjusted the Rakefile to reflect... as for my understanding the
  check for the Host OS could be removed and I did it... don't
  have shoes on Windows set up yet - @ashbb may you please check
  if running the samples still works?
* adjusted README
* [skip ci]
