[style] Remove description attribute, use multi-line comment instead

[GoogleCodeExporter]

I think it would be better to describe a style simply by a standard multiline 
comment.

style BlackAndWhiteStyle {
  description = "A style with white background and black foreground."
  ...
}

/** "A style with white background and black foreground. */
style BlackAndWhiteStyle {
  ...
}

I guess the reason why it is an attribute is to use the description in the 
generator and validation. Actually this can be achieved also by injecting the 
IEObjectDocumentationProvider.

If this is used bu the generator and provides e.g. help messages,  I consider 
this semantically part of the model and in that case I think the description 
field is quite ok.
That way comments are for the DSL developer to explain the model and the 
description attribute is for the end-users.  Different things for different 
purposes.

This is not an issue,  but works as it should.
